Just last week, I added powernowd to the server seed for these reasons
(to load the cpufreq modules and set the governor to 'on-demand' by
default).

If there is a simpler mechanism for accomplishing this (eg, set that
default in the kernel), we could drop the powernowd package from the
server seed as well.
