     I've just discovered today that "ati" driver seems to be able to drive the
  chip also (I'm not in front of the screen, so I can't check it
effectively works,
  but it looks very much like it). RandR seems to work ok with the "ati" driver,
  while it does not with the "radeonhd" driver (everything is equal in both
  setups, I just change the Driver in xorg.con). I'll be seeting in front of the
  screen next week, probably on monday, so I can make further visual tests
  by then.
