This is surprising to me :
- Radeon driver : 
   * starts at wrong resolution 1154 x 864 (or sth) instead of 1400x900
   * GL is slow	extremetuxracer at ~1 fps,
					glxgears 400fps (i know it is not a good benchmark)
					lincity-ng with openGL too slow, unplayable
   * hangs on vt1

- Radeonhd driver :
   * start at good resolution
   * GL is not that slow
					extremetuxracer at ~20fps (until it crashes for obscure reasons)
					glxgears ~800fps
					lincity-ng with openGL playable
   * can go back and forth to vt1-6

Maybe i do something wrong. 
I would be please to have better perf with radeon driver :)
