Atholon 64 Cool'n'Quiet

There is a feature on Athlon chips for reducing clock speed when the processor is idle so keeping the system cooler and using less power.

There is a kernel module to support it but presumably other things need to be done to get it working. For instance gentoo pages describe a file /etc/conf.d/cpudyn with

CPUFREQ_25="/sys/devices/system/cpu/cpu0/cpufreq /sysfs/devices/system/cpu/cpu0/cpufreq"

Does anyone know how to do this in Slackware? I doubt if just enabling it in the BIOS is sufficient.

A bit more hunting around and I have found these two suggestions

Suggestion 1

rc.modules - Uncomment /sbin/modprobe powernow-k8

put in rc.local

if [ -f /sys/devices/system/cpu/cpu0/cpufreq/scaling_governor ]; then
echo -n "Setting Scaling Governor : "
echo -n ondemand > /sys/devices/system/cpu/cpu0/cpufreq/scaling_governor
echo "ondemand"

Suggestion 2

put in rc.local

modprobe powernow-k8
modprobe cpufreq-ondemand

echo -n ondemand > /sys/devices/system/cpu/cpu0/cpufreq/scaling_governor

I guess that apart from the difference in whether or not modprobe cpufreq-ondemand is necessary they amount to the same thing.
