The upstream list for issues with Intel graphics chips is 
intel-gfx at lists.freedesktop.org, but there's probably a fair bit of 
information we should get first.  I've been chasing a pile of 
Sandybridge issues for RHEL6 anyway, so we might as well start here.

The standard reference page for information to collect for debugging KMS 
problems is here:

http://fedoraproject.org/wiki/How_to_debug_Xorg_problems#KMS-related_issues

Ignore the bits about testing the non-KMS environment and the X log, 
they're not going to be relevant for you.  But the video ROM, register 
dump, and dmesg output will all be informative.
