alessio, I think I have taken the wrong approach with this bug. Per your initial report and what information was gathered by apport, the nouveau package was not installed on your computer.
I know that you said that you were able to upgrade to maverick once you removed nouveau but perhaps the issue was something else. Can you check "/var/log/dist-upgrade/" again and attach to this report any and all logs located there. Also attach any Xorg files in "/var/log/"
