[Problem]
Laptop overheads with the -ati driver, idling at 70°C and shutting down with
moderate load.  Overheating does not occur with -fglrx driver.

[Original Description]
Lucid Lynx 10.04 AMD64 Beta 1

xserver-xorg-video-radeon 1:6.12.192-2ubuntu2
xserver-xorg-video-ati 1:6.12.192-2ubuntu2

AMD AthlonTM X2 Dual-Core QL-65 @ 2.1GHz (running stock speed, Cool 'n' Quiet
working, cpu frequency regulation in kernel is working, idles @ 1.05GHz but
temperature still goes up)
AMD M780V Chipset
ATI Radeon 3100 IGP (RV610)
720P video native support (I suppose that means hardware implemented)

Laptop (Toshiba L305D-S5959) overheats when running open source driver. Idles
at around 70°C at room temperature of ~22°C, have BIOS set to shutdown at 95°C
to avoid hardware damage. Computer will shut itself off due to temperature
under moderate load such as viewing flash video in Firefox on hulu.com. This
has been repeated at least 3 times.

Running  the  proprietary fglrx driver 2:8.721-0ubuntu7 (with no other software
changes), the computer idles  @ 45°C (20°C cooler) at room temperature of
~22°C. Watching video on hulu.com does not cause overheating issues.

This is something that could damage computers. If it's under warranty but
Ubuntu is found on the hard drive the manufacturer will probably void the
warranty. I certainly don't want Ubuntu to get that kind of reputation.
