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
PSU fan.

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.

Just because *you* don't want it doesn't make it a disease. :)

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