That's why I suggested to log in from a second computer via ssh.  It's
hard to do anything with a blank screen.

This is expected, the nouveau X driver needs kernel modesetting to work.

It is essential to find out why it does not work.  You might want to try
my suggestion to to log in via ssh and then run "dmesg" after re-loading
the nouveau module.  Boot with "drm.debug=0x04" to obtain additional
information.  Also, try a 3.2.0-rc7 kernel from experimental.

The only available alternative in wheezy/sid is the vesa driver which is
probably not going to suite you.
