Ondemand governor won't work, processor always stuck in high P-state


I can't get my EeePC (Debian Lenny w/ 2.6.26 kernel) to use the ondemand governor. I put a line in rc.local to always enter the ondemand state, and check powertop, but the processor is perpetually stuck in the 1333MHz P-state. I'm getting 8.4W/h and I like to get it down to 8W even at 800MHz.

Should I upgrade to the 2.6.30 kernel in backports to use SHE and KMS? Would that help? I'd have to drag in some sid dependencies with though (acpi.)

Changing C-state governor

I learnt that we can change P-state governors with the command echo "ondemand" > /sys/devices/system/cpu/cpu0/cpufreq/current_governor

How does one change the C state governor ?
