Could you try the latest upstream git repo in case it has been fixed
since 2.3.1 got released?
There's a howto at http://bgoglin.livejournal.com/10936.html

Also, you could try the 2.3.0 driver which was in experimental a couple
weeks ago. You may download it from:
 
http://snapshot.debian.net/archive/2008/04/24/debian/pool/main/x/xserver-xorg-video-intel/
If 2.3.0 works fine, it should be very easy to git bisect and locate the
breaking commit.
