Could you try loading it manually? 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...
