Thanks Conn,
Since it sounds like your issue is fixed with newer Ubuntu, we can close
it. If someone specifically wants the fix backported to Dapper, then a
request specifically for that backporting can be filed. Georg and
Kyle's issues can be tracked on their separate bug reports.

Adding to what Bryce said, my original bug report deals with a 3D
performance regression, not 2D. I believe the problem was that the
i810/Mesa driver in Dapper disabled batchbuffers, causing a slowdown ,
and there were other issues related to Xorg and drm that resolved
themselves from Edgy onwards.
-i810 is an obsolete driver unfortunately, so there's not really anyone
upstream we can escalate to.
However, if you can verify that this issue still exists when using the
-intel driver on Gutsy, we can escalate that way, and hopefully get it
fixed for Hardy. Would you mind testing for the bug on
can someone escalate this please, this is almost unbearable
choppyness/sluggishness, when browsing in firefox or moving windows,
parts of the contents stick to the screen and chop all around like its 2
fps...

Putting aside Xorg-air, this could be the problem. From the LiveCD:
cat /proc/mtrr:
reg00: base=0x ( 0MB), size=1024MB: write-back, count=1
reg01: base=0x3f80 (1016MB), size= 8MB: uncachable, count=1
I'm pretty sure it should be write-combined, something like this (using
Xorg-air
