[Openchrome-users] serious problems with PN800 chip

[Alexander]

Hello, i have VIA PN800 and openchrome 0.2.902-1 driver (kernel 2.6.25) 
There are a few problems with it:
1. glxgears not working correctly - gears not moving! So, it shows fps 
every 5 seconds.
2. I can't change resolution in my desktop environment (xfce 4), there 
is only default item in the list of the possible resolutions.
3. In wine or some games low resolution like a 640x480 is working bad. 
The cursor is moving under wrong places (i think, it can't understand, 
that resolution is changed). So scrolling is appeared then cursor moved 
to right or bottom border of the screen (the virtual screen has an old 
resolution).
4. Broken screen if "EnableAGPDMA" in xorg.conf is not "false".

glxinfo shows that direct rendering: Yes

In file xorg.conf:
...........
Option    "AccelMethod" "EXA"         
Option    "ExaNoComposite"    
Option    "EnableAGPDMA" "false"      
Option    "ExaScratchSize" "8192"
Option    "MaxDRIMem" "16384"
Option    "MigrationHeuristic" "greedy"
