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....
