Let's make sure this custom way of reloading the module is not what
causes the error message quoted below: do you see that too if you boot
directly with nouveau.modeset=1 or nouveau.modeset=0?

I think it's rather xserver-xorg not checking whether EXA support is
available/initialized and assuming the driver has it:
https://bugs.launchpad.net/ubuntu/+source/xserver-xorg-video-ati/+bug/1210316
https://bbs.archlinux.org/viewtopic.php?id=226259

So maybe backporting a newer xserver-xorg-video-nouveau and running it
with our rather old X.Org was not such a good idea :/
