I gave it a shot, but I must admit I'm a bit lost since I'm straddling
between two kernel versions 2.6.38 and 2.6.39. I'm  not quite sure where
to go. I arrived at git://kernel.ubuntu.com/ubuntu/ubuntu-oneiric.git.

I installed various kernel builds from the 2.6.39 line. Here are my
results:

v2.6.39-rc1-natty - broken
2011-04-08-natty - working (daily build from 2011-04-08)
v2.6.39-rc3-natty - working

I examined the commit messages. I'm going to take a wild guess, but it
looks like one of these:

7ccb4a5 drm/i915: Re-enable self-refresh
18b2190 drm/i915: allow 945 to control self refresh (CxSR) automatically
0de009c drm/i915/crt: Remove 0xa0 probe for VGA

Folks have been busy on i915 between Ubuntu-2.6.39-0.0 and
Ubuntu-2.6.39-0.2, which is where the fix seems to be. Hopefully that
helps.
