Looking at the comments, it seems the r200 is still the best overall floss driver supported
I used it in the past but went for an r300 a year or so ago, and I can confirm it's alot
buggier in 3d and slowish in some 2D operations (mozilla, evince/epdf (popler) adobe flash,
gnash). On the positive side, it's a little faster in 3D and some applications, like
openarena, quake3 are rock solid.
