Actually, I need to control CPU speed fairly often:.I need to change
governors and manually set the speed any time I watch full-screen Flash
video from Hulu or Youtube. I have to find the right balance between
required performance and heat/power draw that eventually spins up the
Right now Flash doesn't properly report its CPU load needs, so both
cores remain at minimum, which isn't enough for my R700 card +
xf86-video-ati driver to do all the heavy lifting.
Most of the time I can just leave my desktop and laptop set to the
"ondemand" governor, but as often as I switch to the userspace, an easy
graphical interface would be valuable to me, as a user. Because doing
things in the terminal sucks.

I, too, would like to see this feature. It's useful for at least a few
