The file patch-src-radeon_driver.c has gone. But the problems still occur (but not that harsh as before). I realize on all AMD driven graphicsystems this "bumpyness", even on those graphics cards, HD4830, which are supposed to deliver a acceptable performance for every day's usage, show now a kind of being cut-off and they are no longer faster than the crappy HD4670 or HD4770 which we also use in some FBSD 9.0 boxes.
