In pciconf output you can see "class=0x010601". Your ICH9 controller has PCI subclass 0x06 (SATA) and PCI programming interface 0x01 (AHCI). Driver identified it as AHCI-compatible and used AHCI facilities. Some of PCI ids in ata_intel_ident can be removed today (generic AHCI support will be used for controllers which are identified as AHCI). Some controllers don't identified as AHCI, but can work as AHCI. And they will be handled by ata_xxx_ident. -- WBR, Andrey V. Elsukov
