The machine runs with an i810 video. When restarting the X server about 10 times, you finnally get a message from the kernel: 
agp_release_helper: mem 22 is bound
agp_release_helper: mem 23 is bound

And the X server won't start again. Attempting to start it again result in the following error:
(EE) I810(0): Less than 6MB of AGP memoryis available. Cannot proceed.
(EE) Screen(s) found, but none have a usable configuration.

The only way to fix it seems to reboot the machine.
The XF86Config file is available at

Launch xdm, and hit control-alt-backspace a few times until it refuses restarting.
