Hello, sorry for the delay.
Trying to test this actually had me kind of confused for a bit, because I
discovered that X with UXA enabled will not work if the server has been started
without UXA since the last reboot.
Switching consoles does not crash the server now with 2.6.3, though. In
addition, it's no longer unusably slow when rotated, though it's still a
little stairsteppy and slower than without UXA.
Unfortunately, I can't test chvt switching with UXA enabled now - when I start
the X server with UXA turned on:
Section "Device"
Identifier "ATI Technologies Inc M24GL [Mobility FireGL V3200]"
Driver "intel"
Option "DRI" "true"
Option "AccelMethod" "UXA"
EndSection
If I try to start with UXA enable without rebooting first, I get lots of
this:

but it never manages to draw the display again until I reboot.
