In order to properly deal with GPU reordering of blocks in physical VRAM, Nouveau needs to be able to have better control over VRAM allocations.
Currently nouveau is extremely wasteful and forces massive amounts of padding/alignment to avoid buffer corruption issues.
radeon/vmwgfx haven't been tested, but nouveau works as well as it did previously.
