Despite all of this I still see no reason why a driver could not
expose the static, real frambuffers via private ioctls. You can get
all your fancy acceleration that way. Then fix user-space to use this
API. If enough drivers end up with something similar, move it into the
core. Just like we always do in DRM.

I don't care so much about userspace in my specific use case, more
about fbcon, which I think can be solved without too many hoops.

As for FB objects, my thinking is we could just use
unmap_mapping_ranges() to effectively change the mapping under the hood
of the app so it alternatively maps a bit of fb or a bit of memory...
