Thanks Nathan, You pointed me in the right direction. 

After changing my windowmanager to xterm, 
i noticed that mouse and keyboard aren't detected because hal was not running.
Because of this i couldn't do anything on the screen :).

Yes, Without this i just get some pixels moving on the screen and the console
does not recover after terminating the process. 
From what i read on the list, it may be because DRI
is broken. I will have to try to disable it.

Unfortunately w/o Acceleration everything is pretty slow, even console scrolling in x-term

The relax_mmap check is default in 10.x. My monitor gets probed correctly.
