Sorry I have just installed 3.2.16, but have yet to reboot this
machine...

On Debian SID (since always), in Kernels 2.6.2x and 2.6.3x the userspace
stuff was broken for my laptop while on AC power, forcing it to 800MHz
on its cores down from 2207MHz... so I had to remove the modules all the
time to get it to run at 2207MHz when I needed it to. When I was on
battery power, things worked properly.

Since 3.0.0-rc1, everything seems to work properly.

Hope this helps.
