Thank you Andres :)
I experienced a similar problem after upgrading to a new kernel today in
squeeze, I noticed the resolution of the screen in text-mode had
changed, and X wouldn't load.
Since it was a kernel update, I'd figure I would recompile my nvidia
driver modules (proprietary nvidia driver). The nvidia installer failed
however and looking on this list I saw your message, blacklisting
nouveau allows me to load the nvidia driver again (I need some of it's
features, nouveau doesn't handle my setup very well yet, mostly 3D
acceleration).
It looks to me like the nouveau module is conflicting with (any?) other
drivers.
