Comment 19 for bug 555595

So it looks like the problem appeared in the .18->.19 release, and there aren't many patches in there that touched the i915 driver. I'll investigate and perhaps build a test kernel that backs out the patch(es).

There was a patch that went in to disable FBC for 915GM and 945GM devices, to prevent some suspend/resum problems.

That was for launchpad bugs 492392 and 539609.
