Bug Description
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.
Full Xorg.0.log and lspci attached

The radeon driver mostly works for me, but I get distracting light snow and occasional horizontal lines flickering across the screen. I've tried to capture some close-up images with my camera which I'll attach to this bug. The worst corruption is at the far right of the screen.
I don't see the problem with the radeonhd driver. I've tried to switch to the radeon driver a few times but always run into this snag.
I'm running Ubuntu Jaunty with ati_drv.so from xf86-video- ati-6.12. 2-76-g2c8e130
My hardware is an HP t5735 thin client with onboard x1200:
$ lspci | grep VGA

I'll attach configs, logs and the photos
