drmAgpAcquire failed 1023

[Fazer]

time to time I try to lunch 3D on my Unichrome pro IGP card using a openchrome 
driver 32 MB shared memory set in bios.

After some months Iresolved why I can't compile it but now i have those 
problem it apper in /var/log/Xorg.0.log 

exacly everything is god excluding this:

and dotclock.

So what is wrong
