<pre>I talked to Ben about this bug at XDC2012 and he told me we are using
nv04-style virtual memory interface, because of some then unknown bugs in nv4x
implementation - and this is probably the reason why you are seeing this bug.
Since XDC, Ben fixed and enabled nv4x-style virtual memory in nouveau.git, so
please test it!</pre>
