I notice that several people reporting this bug have Xorg.0.log files showing that Direct Rendering is disabled. Reporters also seem to have 810 chipsets.

The changes made between ubuntu2 and ubuntu3 were backports of various bug fixes from the 1.3.99 branch. Presumably one of those patches broke something for i810.

Patch 245 is of interest since it describes a situation where DRI is disabled: "Fixes issue where if DRI is disabled, GL_MAX_TEXTURE_COORDS_ARB value is not returned correctly from glGetIntegerv()." But that's just a guess; any one of the bugs could be causing this regression.

I've built some versions of xserver that each disable different patches from that ubuntu3 version. Those of you experiencing this issue, please install and test each of these to see if they correct the behavior. Depending on which one(s) work, that will help narrow down the fix. If my hypothesis about patch 245 is correct, then ppa1 and ppa2 will fail, but ppa3 and pp4 will work.
