ATI Radeon video performance drop when laptop heating up

Dear all,

I am using xorg 2.6.8 on an ASUS laptop with a Radeon Mobility M7 LW graphic 
card. The laptop is configured with Debian + Ubuntu xorg packages. 

I was too lazy to install xorg from source.

xorg is configured with DRI and XV. Playing a DVD under xine only consumes 40% 
of the computer activity. But when the laptop warms up, activity climbs to 

The performance of OpenGL software (like glxgeras) stays the same, but 
performance of video playback drops dramatically.

Are you aware of any relation between a laptop temperature and the performance 
of a video card? Is there a way to playback video with good quality, even 
when the laptop heats up?

Kind regards,
