Uhm.. at least my Mobility Radeon HD3650 runs very *hot* as a default.. so hot
that most/many liveCD Linux distros crash before the computer boots to the
desktop. Or then Linux does emergency thermal shutdown halfway the boot
sequence as a safety measure.. 

The default radeon driver power_profile ("default") seems to be broken at least
on this graphics card. When I manually switch to power_profile "low" the
temperature of the laptop goes down 10-20 degrees celsius.

Oh, this is good news. Any more info about it? 

Thanks,
