I think I've seen your XFree86 config file - do you run in 16bpp mode?
I only recall seeing the problem in 24bpp mode with XFree.

PS. I've updated my page with info about the graphics card problems -

Linux-laptop.net still hasn't processed my submit last month for this
page, so I guess it is a lesson in patience.

I haven't noticed it myself, although I tend to get cranky and touchy
myself when it gets into the low 80's, so I haven't necessarily
operated the laptop in the conditions such as your (I *do* have air
conditioning :-).
The only thing I have noticed is random lockups from time to time
where the X server locks up and needs to be restarted. But that's
probably an XFree86 4.3 bug....
