Keith Packard is the Intel guy who has been working on the kernel and 
xorg drivers for Intel graphics chipsets.  Right now, they are farther 
ahead than any others, having come thru a year of extremely intense 
change.  /If/ you are running fully upto date xorg video driver and 
kernel, things /should/ be calming down now, some, and it's rather likely 
that he could use your bug filings and etc.  If either your xorg or 
kernel is /not/ upto date, if you are /not/ running kernel 2.6.30.x or 
even the 2.6.31 rcs, or the corresponding xorg xf86-video-intel drivers, 
2.8.0 it looks like with a quick check on Gentoo, do try updating.  With 
the Intel drivers, it's likely to make a difference.  If the problem 
persists with upto date drivers, then as I said, Keith is likely to be 
particularly interested in your bug, because he /is/ working very hard on 
stabilization, ATM.

Also, what you have in your xorg.conf could be important.  I'm not 
running Intel hardware myself (except on my netbook which I've not done 
much with of late, it's still running what it came with, some Linux 
distribution I had never heard of before) so can't give you any pointers 
based on personal experience, but whether you're using XAA or EXA or UXA 
2D accel may be critically important, as well as some other settings in 
xorg.conf, whether you're running OpenGL or only XRender in KDE, etc.

The good news is that the Intel drivers /are/ ahead of everyone else, and 
the worst changes are behind you, while Radeon users are just starting 
the set of changes to bring them upto date, and nVidia... well, with 
their mix of proprietary and open, they're a story unto themselves.  So 
if Intel drivers aren't working right now, they should in the near future 
as things calm down and everything stabilizes once again.
