OK, good, “just” a segfault. Is there any chance to install debugging
packages (xserver-xorg-core-dbg and xserver-xorg-video-nouveau-dbg),
and to run X inside gdb, so as to get a full backtrace?

If that makes things easier for you, you can get a core dump first,
and then get the full backtrace out of it, post-mortem.
I'll try to do it

Yeah, I failed to phrase my question properly. The idea was to
determine whether you were running “just” a 2.6.32(.y) upstream
release, or whether you had some patches on top of it. Since you're
using Debian's source, that's alright, you should have DRM patches,
which is good. (It might be nice to know which exact kernel version
you fetched through apt-get source, though.)
The version.Debian in the source contains : 2.6.32 23
