Thanks for testing anyway.

With the mga driver, it may be because it hasn't adapted to changes in
the XAA RENDER acceleration interface, so RENDER isn't currently
accelerated with it. The radeon driver has adapted to this though, but
you may still want to check in the log file that RENDER acceleration is
enabled (and/or just send the full log to this report :).
There were few changes in the XAA code between 6.8 and 7.0, and none of
them look relevant to this problem, but it's possible that changes in fb
or another X server component could be relevant.
