It is a different part of the company but I did look at this enough to
know the answer to that question at least. It is a different 2D engine
but there is enough code in the public code to work out how to use the
2D bits. The modesetting part is very i915 like and its possible to
share it, I've shared patches to that end in the past although sadly
they ended up not being merged.

Right, I'm not sure how much the 2D engine alone buys us. You'd be able
to something certainly but how far you can get I don't know.

Cheers,
