--- Comment #21 from Florian <linux at wolke7.net> ---
Same situation on my Lenovo T500 Notebook with the following card:
01:00.0 VGA compatible controller: Advanced Micro Devices [AMD] nee ATI RV635
[Mobility Radeon HD 3650]
If my Notebook is in IDLE-state the temperature stays about 75° and I hear the
noise of the fan nearly all the time. Heavy load increases temp to over 90° and
it will shutdown due to the overheating limits of kernel.
My workaround is switching to intel hd graphics in bios because setting power
profile to low seems to be slower than using the integrated graphics adapter.
Thats obviously no real solution because I want to use the full power of the
ati graphics card without switching to fglrx driver.
