** Description changed:

  Since update to Jaunty, I'm experiencing very strange bug when using high 
resolution (1600x1200).
  Some kind of static noise (a bit like on TV without antenna) is displayed 
continuously. As this "snow" is white, it's particularly annoying on black 
background.
  
   My screen is Wacom Cintiq 21UX and can handle this resolution
  (1600x1200) using this refresh rate (60Hz).
  
  Curiously this doesn't occurs with lower resolution as 1280x1024 I
  switched to using xrandr.
  
  No change using XAA or EXA.
  
  Remarkable output on Xorg.0.log is :
  (WW) RADEON(0): DRI init changed memory map, adjusting ...
  (WW) RADEON(0):   MC_FB_LOCATION  was: 0xefffe000 is: 0xefffe000
  (WW) RADEON(0):   MC_AGP_LOCATION was: 0x003f0000 is: 0xffffffc0
  for warning, and 
  (EE) RADEON(0): Unable to reserve offscreen area for back buffer, you might 
experience screen corruption
  for errors. No idea if related to my problem. Last log (error) doesn't occurs 
ou xserver startup, but while using. Seems related to OpenGL context creation.
