Bug#515512: X freezes for me too

[Sir Jective]

When I run Nexuiz, the system freezes after a few seconds, and after 
reboot there are a number of lines saying "tossed event which came in 
late" in Xorg.0.log.old.
This does not occurr with ATI's fglrx driver.

I'm using a stock Lenny Xserver and kernel (686, not tainted).

01:00.0 VGA compatible controller: ATI Technologies Inc Radeon R350 
[Radeon 9800 Pro]

The freeze does not occur if I reduce agp mode from 8x to 4x (8x works 
with fglrx, though).
