That would be a "someone" at Tungsten Graphics, then ;-). And presumably for the radeon and r300
drivers too?

This is sounding like "Fedora 8" material...

Interesting, because I'm currently not using the "XaaNoOffscreenPixmaps" option at all: compiz
performance is not amazing, but is OK. Would I lose access to the second 128 MB of my 256 MB
Radeon 9200 card if I did use it? The Xorg.0.log file says that it can only access the first 128
MB on my card directly.

Cheers,
Chris
