Sorry for the slow response.  This is

	BUG_ON(!atomic_read(&bo->tbo.reserved));

Is it reproducible?  There have been some ttm fixes in squeeze,
so it would be interesting to hear how a recent squeeze kernel
behaves.

If it isn't reproducible, we can declare victory --- great.
Otherwise, please test a kernel from sid or experimental as well;
the only packages from outside squeeze aside from the kernel
imaging itself that should be needed in order to do so are
linux-base and initramfs-tools.

If it is reproducible with a 3.x.y kernel, we can take this
upstream.  If it is reproducible in squeeze but not in sid, then
we can try a few versions halfway between from snapshot.debian.org
to narrow down when the fix was introduced, to find patches to
try applying to squeeze.

Thanks and hope that helps,
Jonathan
