Ah... yes. I am confused though, why keep powernow_k8 as a separate module as
opposed to an alias?

Neither acpi_cpufreq nor powernow_k8 is loaded automatically which of course
leads to failure of all custom units configuring ondemand governor via
sysfs. Manually modprob'ing acpi_cpufreq does work and indeed properly scales
down the frequancy, but is accompanied by an info-level kernel message
"acpi-cpufreq: overriding BIOS provided _PSD data".

So, if the cpufreq driver works OK for other AMD users, I'll happily blame
asus...

Thanks,
Leonid.
