Hi Nate,

This is what I get on a TP T41, do the cpufreq results below look right?
Also if I loaded both modules all I got for dev.cpu.0.freq was -1 or 1700 and no 
levels.

CPU: Intel(R) Pentium(R) M processor 1700MHz (1698.56-MHz 686-class CPU)
   Origin = "GenuineIntel"  Id = 0x695  Stepping = 5

   Only acpi_perf loaded at boot:
+acpi_perf0: <ACPI CPU Frequency Control> on cpu0

# sysctl dev.cpu|grep freq
