My laptop (sony vaio pcg-v505bx) has a Pentium 4 M, but not Centrino (which name is... Pentium 4 M too), afaik it's capable to support speedsted, (enhanced or not?).

My processor also supports for speedstep and dmesg looks like: #dmesg|grep CPU CPU: Mobile Intel(R) Pentium(R) 4 CPU 2.30GHz (2224.01-MHz 686-class CPU) in the est.c code i found out the followig: ....... err = kernel_sysctlbyname(curthread, "hw.model", hwmodel, &modellen, NULL, 0, NULL); ....... if (strncmp(hwmodel, "Intel(R) Pentium(R) M processor", 31) but my sysctl hw.model returns hw.model: Mobile Intel(R) Pentium(R) 4 CPU 2.30GHz The same as in dmesg. Changing the code to find a substring Mobile in hw.model delivers system stuck at the module load time. -- Best regads, Anton Nikiforov --------------ms030601040806090509050002 Content-Type: application/x-pkcs7-signature; name="smime.p7s" Content-Transfer-Encoding: base64 Content-Disposition: attachment; filename="smime.p7s" Content-Description: S/MIME Cryptographic Signature MIAGCSqGSIb3DQEHAqCAMIACAQExCzAJBgUrDgMCGgUAMIAGCSqGSIb3DQEHAQAAoIII7TCC AtEwggI6oAMCAQICAwvaFTANBgkqhkiG9w0BAQQFADBiMQswCQYDVQQGEwJaQTElMCMGA1UE ChMcVGhhd3RlIENvbnN1bHRpbmcgKFB0eSkgTHRkLjEsMCoGA1UEAxMjVGhhd3RlIFBlcnNv bmFsIEZyZWVtYWlsIElzc3VpbmcgQ0EwHhcNMDQwMzA1MjExMjI4WhcNMDUwMzA1MjExMjI4 WjBEMR8wHQYDVQQDExZUaGF3dGUgRnJlZW1haWwgTWVtYmVyMSEwHwYJKoZIhvcNAQkBFhJh bnRvbkBuaWtpZm9yb3YucnUwggEiMA0GCSqGSIb3DQEBAQUAA4IBDwAwggEKAoIBAQC1Ps7E cf3xTnaY72Aip/U5HeUmGwQ6QmbCjMcqS3XfO6EsA+5ol526JvhQ1XStpDX/kh8R8MDELUJD SVooXFiDInspw5tmPOlXV1C60xH4VWf5Gh+2y3yDGzHyWBAalul7LbhC1p8zDNUA12pAu4Ry 1k1A0Yepomr8CRbh/Z9JryfJcqHYDL+z1qgLzQlpJsao9E3Zld5ZfgJPORcFoRB7Z6jvqVLh pLNmSrvfDbSw6WK/K9EbZT9zlOTlmOnt4uLBy3hKZMcvkaFrYVYTRXLMegJHFPAp3sxLYef2 iW9fEUKgrs4W7d5c8UWlmiGurVt1Xdzc58W8X3vekMLqu9elAgMBAAGjLzAtMB0GA1UdEQQW MBSBEmFudG9uQG5pa2lmb3Jvdi5ydTAMBgNVHRMBAf8EAjAAMA0GCSqGSIb3DQEBBAUAA4GB ABINGnCD0TGnBHqGYbJHSwjFfxEsVS1ygSUVIyb0Q1S0SphgUSeRWIZ4+joWR9TzxFGqLtYM TEQvRTQ7VJcugjn2o2nTgQ4EPhze0O5ki2eUWHE9dViHboQWOWI0r1vurUTkDnmloeM8mpMo CAAtXbjyhz7AVKUwI7vULQKuE+imMIIC0TCCAjqgAwIBAgIDC9oVMA0GCSqGSIb3DQEBBAUA MGIxCzAJBgNVBAYTAlpBMSUwIwYDVQQKExxUaGF3dGUgQ29uc3VsdGluZyAoUHR5KSBMdGQu MSwwKgYDVQQDEyNUaGF3dGUgUGVyc29uYWwgRnJlZW1haWwgSXNzdWluZyBDQTAeFw0wNDAz MDUyMTEyMjhaFw0wNTAzMDUyMTEyMjhaMEQxHzAdBgNVBAMTFlRoYXd0ZSBGcmVlbWFpbCBN ZW1iZXIxITAfBgkqhkiG9w0BCQEWEmFudG9uQG5pa2lmb3Jvdi5ydTCCASIwDQYJKoZIhvcN AQEBBQADggEPADCCAQoCggEBALU+zsRx/fFOdpjvYCKn9Tkd5SYbBDpCZsKMxypLdd87oSwD 7miXnbom+FDVdK2kNf+SHxHwwMQtQkNJWihcWIMieynDm2Y86VdXULrTEfhVZ/kaH7bLfIMb MfJYEBqW6XstuELWnzMM1QDXakC7hHLWTUDRh6miavwJFuH9n0mvJ8lyodgMv7PWqAvNCWkm xqj0TdmV3ll+Ak85FwWhEHtnqO+pUuGks2ZKu98NtLDpYr8r0RtlP3OU5OWY6e3i4sHLeEpk xy+RoWthVhNFcsx6AkcU8CnezEth5/aJb18RQqCuzhbt3lzxRaWaIa6tW3Vd3Nznxbxfe96Q wuq716UCAwEAAaMvMC0wHQYDVR0RBBYwFIESYW50b25AbmlraWZvcm92LnJ1MAwGA1UdEwEB /wQCMAAwDQYJKoZIhvcNAQEEBQADgYEAEg0acIPRMacEeoZhskdLCMV/ESxVLXKBJRUjJvRD VLRKmGBRJ5FYhnj6OhZH1PPEUaou1gxMRC9FNDtUly6COfajadOBDgQ+HN7Q7mSLZ5RYcT11 WIduhBY5YjSvW+6tROQOeaWh4zyakygIAC1duPKHPsBUpTAju9QtAq4T6KYwggM/MIICqKAD AgECAgENMA0GCSqGSIb3DQEBBQUAMIHRMQswCQYDVQQGEwJaQTEVMBMGA1UECBMMV2VzdGVy biBDYXBlMRIwEAYDVQQHEwlDYXBlIFRvd24xGjAYBgNVBAoTEVRoYXd0ZSBDb25zdWx0aW5n MSgwJgYDVQQLEx9DZXJ0aWZpY2F0aW9uIFNlcnZpY2VzIERpdmlzaW9uMSQwIgYDVQQDExtU aGF3dGUgUGVyc29uYWwgRnJlZW1haWwgQ0ExKzApBgkqhkiG9w0BCQEWHHBlcnNvbmFsLWZy ZWVtYWlsQHRoYXd0ZS5jb20wHhcNMDMwNzE3MDAwMDAwWhcNMTMwNzE2MjM1OTU5WjBiMQsw CQYDVQQGEwJaQTElMCMGA1UEChMcVGhhd3RlIENvbnN1bHRpbmcgKFB0eSkgTHRkLjEsMCoG A1UEAxMjVGhhd3RlIFBlcnNvbmFsIEZyZWVtYWlsIElzc3VpbmcgQ0EwgZ8wDQYJKoZIhvcN AQEBBQADgY0AMIGJAoGBAMSmPFVzVftOucqZWh5owHUEcJ3f6f+jHuy9zfVb8hp2vX8MOmHy v1HOAdTlUAow1wJjWiyJFXCO3cnwK4Vaqj9xVsuvPAsH5/EfkTYkKhPPK9Xzgnc9A74r/rsY Pge/QIACZNenprufZdHFKlSFD0gEf6e20TxhBEAeZBlyYLf7AgMBAAGjgZQwgZEwEgYDVR0T AQH/BAgwBgEB/wIBADBDBgNVHR8EPDA6MDigNqA0hjJodHRwOi8vY3JsLnRoYXd0ZS5jb20v VGhhd3RlUGVyc29uYWxGcmVlbWFpbENBLmNybDALBgNVHQ8EBAMCAQYwKQYDVR0RBCIwIKQe MBwxGjAYBgNVBAMTEVByaXZhdGVMYWJlbDItMTM4MA0GCSqGSIb3DQEBBQUAA4GBAEiM0VCD 6gsuzA2jZqxnD3+vrL7CF6FDlpSdf0whuPg2H6otnzYvwPQcUCCTcDz9reFhYsPZOhl+hLGZ GwDFGguCdJ4lUJRix9sncVcljd2pnDmOjCBPZV+V2vf3h9bGCE6u9uo05RAaWzVNd+NWIXiC 3CEZNd4ksdMdRv9dX2VPMYIDOzCCAzcCAQEwaTBiMQswCQYDVQQGEwJaQTElMCMGA1UEChMc VGhhd3RlIENvbnN1bHRpbmcgKFB0eSkgTHRkLjEsMCoGA1UEAxMjVGhhd3RlIFBlcnNvbmFs IEZyZWVtYWlsIElzc3VpbmcgQ0ECAwvaFTAJBgUrDgMCGgUAoIIBpzAYBgkqhkiG9w0BCQMx CwYJKoZIhvcNAQcBMBwGCSqGSIb3DQEJBTEPFw0wNDA4MTgwMDMxMTJaMCMGCSqGSIb3DQEJ BDEWBBTOMI62/48OJ3A6dF4+YHCMIGNECzBSBgkqhkiG9w0BCQ8xRTBDMAoGCCqGSIb3DQMH MA4GCCqGSIb3DQMCAgIAgDANBggqhkiG9w0DAgIBQDAHBgUrDgMCBzANBggqhkiG9w0DAgIB KDB4BgkrBgEEAYI3EAQxazBpMGIxCzAJBgNVBAYTAlpBMSUwIwYDVQQKExxUaGF3dGUgQ29u c3VsdGluZyAoUHR5KSBMdGQuMSwwKgYDVQQDEyNUaGF3dGUgUGVyc29uYWwgRnJlZW1haWwg SXNzdWluZyBDQQIDC9oVMHoGCyqGSIb3DQEJEAILMWugaTBiMQswCQYDVQQGEwJaQTElMCMG A1UEChMcVGhhd3RlIENvbnN1bHRpbmcgKFB0eSkgTHRkLjEsMCoGA1UEAxMjVGhhd3RlIFBl cnNvbmFsIEZyZWVtYWlsIElzc3VpbmcgQ0ECAwvaFTANBgkqhkiG9w0BAQEFAASCAQB0HgQy ssL3qtST3VJTxKVKqrs2gpopYNsVyEK7p1bOF4aJriXw000hE0jtHeiCmAhNiJylmbh6yho8 FIy6X4ZwE7SFiCmfgr87kX3qNzYbFwnEMXKyEDFwKxMpOOIT93eWYcJk9ysAV7kQp9l9rJDT yJ65xTCQV1UCmPV0/kKBr5NRkMpGlrIBma57wEDoXhyGIVdL06WM+vDuuXRyKYCyIarUoSRP G3xZrtn4xwpb9XxyDWKVjveRPDKsOf1jA7YHW3TwogOIT7CNi5/eA4l4zVxZf0nWfrwMHLV2 J3OVteuH/yllLZmPRrmsB/STv5kP44Ufix9hccf1Pq+3TmBXAAAAAAAA --------------ms030601040806090509050002--
