If you are starting at runlevel 3 there will be no kdm/gdm/xdm greeter
Thus I take that the display is _not_ black but there is still nothing relevant
on it

AFAIK the above message is not crucial
There are a few things you can try - all without loading X
1. Play with the module options "noaccel" and/or "nofbaccel" (modinfo nouveau
for more info)
2. Select different resolution - append "video=..." [1] to your kernel command
line
3. Add some printf() statements in the kernel module to narrow in which state
the issue occurs
Cheers
