No, but it needs physically-contiguous memory (and you can't count the 811M
here, as it can only use already-free memory at this point).

This depends on the memory usage pattern. Maybe something changed in UVM
that makes the problem worse, but it has always been there.

I agree it should be fixed, but it's not that easy (and, BTW, the agp driver
has the same requirements, and so the same problem).
