Sure, but we need to set one afaics because...

...we are I/O bound often during startup afaics (at least these days)
and the CPU is often fast enough when on lower frequency.

Currently the default kernel gov is userspace:

$ grep DEFAULT_GOV /boot/config-2.6.20-1.2997.fc7

So no power savings until something takes care of it afaics (or am I
wrong with that? anyway, that could probably easily be adjusted until F8).
