See commit ace77b6b1304 in xserver-xorg-video-nouveau for the reason:

disable fermi accel on 0.0.16 interface
Kepler accel support broke some assumption made by the older kernel
interface, and Fermi shares the same code. It can't work (without
some annoying hacks anyway) with the 0.0.16 kernel anymore.

Note that this is actually an uncompressed tar archive.
I wonder what happens if, during the wheezy+1 release cycle, the Nouveau
DDX or the mesa driver starts depending on other features present in
Linux 3.4 but not in Maarten's patchset.

We need someone with a Fermi card that is supported (i.e. there is
working microcode) by Linux 3.2.
Should we upload xserver-xorg-video-nouveau to unstable and wait for
complaints? The version in sid is unusable anyway[1] :-/, so breaking
acceleration for some users might not be such a big deal.
Cheers,
Sven
