rv250 here, CVS HEAD X.org, Meas CVS Head DRI driver, current bk kernel (well, actually, all of the above are about 5 days old, doesn't have Vladimir latest fixes), I get very jerky display with g117 and broken textures, ultimately it locks up after moving the mouse a little bit (at the meny screen). I can kill X tho, that works, so the chip/bus isn't totally dead (or it recovers with an engine reset).
