Hey again,

Ah, that makes sense.

When you get the black screen, is the machine still usable?  E.g., can
you ssh into it, or can you run commands "blindly"?  Does ctrl-alt-delete
work?  Does the magic sysrq key work?  Can you see text on the screen
if you use a bright flashlight to look at it?

Hopefully something like the following can work:

	dmesg >log.before && modprobe nouveau && dmesg >log.after

It might also be possible to get the relevant information from
/var/log/dmesg or /var/log/dmesg.0 after rebooting.

Sorry for the slow response, and hope that helps.
