Hello,

has anyone gotten it to work? I can not enable it:

root@deepdance:/sys/devices/system/cpu/cpu0/cpufreq -> 
  echo "ondemand" > scaling_governor ; cat scaling_governor
userspace

I am using kernel 2.6.12-2.

-> lsmod | grep ondemand
cpufreq_ondemand        5116  0

root@deepdance:/sys/devices/system/cpu/cpu0/cpufreq -> 
  cat scaling_available_governors
ondemand userspace performance

Governor "userspace" works nicely with powernowd.

And I also can set the governor to "performance". Does "ondemand" need 
more than two available scaling frequencies?

root@deepdance:/sys/devices/system/cpu/cpu0/cpufreq -> 
  cat scaling_available_frequencies
1130500 731500
