cpufreq governor vs. powernowd

[Dmitriy Kropivnitskiy]

The "ondemand" governor should actually increase your power savings, 
since it is able to react much faster to CPU utilization changes. So the 
delay between your CPU going idle and getting into lower freq mode is 
going to be smaller. Otherwise, I think that setting "performance" 
governor when adapter is plugged in is not going to change things much. 
Follow the link I had in the original post and look at the benchmark, 
the difference between performance and ondemand is marginal.
