Could you please try a 3.5 kernel from experimental, and report a new
bug upstream if that problem persists? See
http://nouveau.freedesktop.org/wiki/Bugs for instructions.
Besides booting with nouveau.noaccel=1, you could also try to use the
"NoAccel" option in xorg.conf (see nouveau(4)), or use the new
xserver-xorg-video-modesetting driver.
