OK. Blacklisting the nouveau kernel driver is already taken care of by
nvidia-kernel-common, including rebuilding the initrd. (initrd handling
is only in wheezy+sid, not in squeeze)

Pure existance of the lib is not a problem. Very good.

So now it's only xserver-xorg-video-nouveau remaining as a candidate.
Could you reinstall it and if the problem reappears, send the following:
* your xorg.conf (and/or xorg.conf.d/ snippets)
* /var/log/Xorg.0.log without xserver-xorg-video-nouveau being installed
* /var/log/Xorg.0.log after hanging
Removing xserver-xorg-video-nouveau afterwards should fix it again.

Thanks
