[Xorg] R100/R200 render acceleration

Attached to that bug is a patch for Render acceleration on R100 and
R200.  I'm running the R200 stuff on my desktop, and R100 seems just as
good in the little testing I've done.  I'd appreciate if adventurous
folks could try the patch and report any issues in that bug, so we don't
get any surprises when it's committed.  Note that it's only enabled when
the DRI is working.
