Ok, two problems:

1) The driver doesn't detect any modes. Does is somewhat work with
Option "noRandR" ? I assume it doesn't detect any modes either, and
crashes at the same place.
2) Even in this case it shouldn't crash.

[Switching to Thread 0x2b1260b587f0 (LWP 5811)]
0x00000000004763e7 in xf86InitViewport (pScr=0x804260)
at ../../../../hw/xfree86/common/xf86Cursor.c:105

Clearly accessing pScr->modes->HDisplay. This can only fail with
modes == NULL.

We can emulate the case of not getting any modes, and fix the crash, but
why no modes have been found in the first place is another thing.

I think this is something Luc wants to handle, probably your connector
tables are wrong / misparsed. The log tells me that no monitor was found
at all.

Still, the server should fail gracefully :)
