Sure, apologies. The newest g-p-m in CVS now defaults to ondemand for
both AC and battery, so that part of the problem is solved.

If you really want to disable the cpufreq stuff, I think you can just
change /apps/gnome-power-manager/cpufreq_ac_policy
and /apps/gnome-power-manager/cpufreq_battery_policy to "nothing" and
then g-p-m should ignore the setting. This is untested, so please tell
me if this works okay.

Cool, thanks. Stuff like video resuming should also get a bit better
when pm-utils is used by the big distros, and we are working on that
now. Expect more coolness. :-)
