Thanks a lot for this upload Bryce. I'll be using UXA for jaunty so this
will be a big improvement for my experience.

I've done some testing with 2.6.3 plus the new xorg. I have a better gut
feeling about this version, no spontaneous xorg crashes yet (even though
I can get it to crash easily using repros of known bugs, see below).

Also; I've found one new regression (which I suspect is G45 only?). It's a kerneloops
warning (a warning + backtrace printed to dmesg) that is being printed right
after every boot using both EXA and UXA (I don't see anything "bad" about the
system though and even though it says "slowpath" the perf I get in UXA after
seeing this message is really fast, certain much better than EXA perf):

Bug status:
- transparency defect with compiz + UXA (still repros)
Which I think is closely related to this bug as well:

- hyperspace screensaver still SEGV's the xserver in UXA and in EXA on G45

- opening big JPG file in firefox doesn't crash anymore but
instead of the actual JPG I just get black area (plus nasty stuff in dmesg,
see bug report for new comment):
