Honestly I do no believe you have is not caused by nouveau, moreover it's an underlying ACPI problem causing nouveau to fail - note the ACPI errors

you can bisect the problem as it would ease and fasten the resolution
Adding [bisected] to the bug [1] and CC the author of the patch would be
encouraged

Sorry for the delay.
I would like to help, but any link helping me to understand what to do
to "bisect"...?
I'm using a fedora kernel. I know that if I boot with
kernel-3.3.7-1.fc17.x86_64 it works, while any other following kernel
released not
(right today I tried with kernel-3.4.4-5.fc17.x86_64).

Thanks,

"Code Bisection is a method used in software development to identify change
 sets that result in a specific behavior change. It is mostly employed for
finding the patch that introduced a bug. Another application area is finding
 the patch that indirectly fixed a bug." [1]

In other words in order to get it up and working it is encouraged to dig deep
into the issue and recompile the kernel a few times. Refer to
"Building a custom kernel" [2] or "koji bisecting kernel builds" [3]
for more information
