GEM VRAM could implement PRIME helpers, which would allow for using the generic fbcon.

bochs_gem_prime_*() functions with this series applied look like you can just rename them & move over to vram helpers.

It's not a full prime implementation, specifically actual export/import isn't there. But pin+vmap (needed by generic fbcon) is implemented.

I did have a patch to do this, but then I read that prime requires DMA for buffer sharing and bochs works only because it's emulated. If bochs' implementation is complete enough to be useful for other drivers, I'll add it to the patch set.
