I've looked into this while working on splitting VRAM allocations into
smaller nodes and the answer is nope, not at all.
We would pretty much need to rewrite whole TTM from BO based to page
based. Otherwise you just have way to much overhead with all those ttm
And when we really want this step I would rather wait for HMM to land
and use that instead.
