Hey Maarten,

Thank you very much for these patches! I myself was wondering what to
do about XAA today, so these came at the right time. I forwarded them
to the Geode X.org list so that everyone can review them.

Please note that reverting the default acceleration for the GX
component to EXA won't work, because that component's EXA support is
buggy and outdated and, if you look at the upstream ChangeLog, you'll
notice that we had reverted to XAA as a kludge. None of the current
Geode developers seem to have access to GX hardware to test or
sufficient knowledge of the X.org internals to blindly fix the code,
so it has remained unfixed.

Cheers!
