Emil, I tried following your advice, using the original driver which comes with
kernel 3.0.0-git3 but the problem is still there (it gets stuck on an
unresponsive black screen which only displays a small underscore "_" in the top
left corner and I do not get the gdm greeter).

I am going to attach the logs (as file
nouveau-discrete-with_Accel-kernel_3.0.0-git3-driver-no-aiglx-do_not_require_glx.txt),
but I am sure they are very similar to the previous ones except from AIGLX
being disabled and GLX loading only once (by default).

I will keep those two settings as you suggested from now on, but so far nothing
has changed unfortunately !

Next I will try the kernel driver from the snapshot (commit
4fc2e2fc0157433883f10e0d7327c73069c66d63) on the 3.0.0-git3, but at this point
I really doubt it would sort things out.

I am not sure but perhaps the only difference between the kernel module shipped
with the upstream kernel and the out-of-place kernel module from the snapshot
is that the following line is missing in the snapshot:

[drm] nouveau 0000:01:00.0: Pointer to BIT loadval table invalid

Other than that with kernel 3.0.0 there was no practical difference between the
two kernel drivers (upstream and freedesktop snapshot).
