it should be k8 as far as I know.I have Asus K8V-MX mobo with Sempron 2600+ which does support Cool 'n Quiet in Windows, but apparently it doesn't work well with Powernowd in Linux.
I tried modprobe powernow-k8, modprobe acpi-cpufreq and even modprobe powernow-k7 but they all give the same error:
Guess I'm out of luck here, or what?Code:# modprobe powernow-k8 FATAL: Error inserting powernow_k8 (/lib/modules/2.6.15-26-k7/kernel/arch/i386/kernel/cpu/cpufreq/powernow-k8.ko): No such device
