I have an Athlon 64 3800+/Nforce 3-250Ultra system running Fedora Core 3
with a custom 2.6.9 kernel. In the kernel configuration the performance,
userspace, powersave and ondemand performance governors have all been
selected however the
/sys/devices/system/cpu/cpu0/cpufreq/scaling_available_governors
file lists only performance and userspace. I've tried to add powersave and
ondemand to the file but it reverts to just userspace performance. How do
I get the kernel to support powersave and ondemand. Ondemand seems like a
particularly useful power governor.
