I'm not actively working on it right now... Radeon is using TTM as the
backend, while presenting a GEM api to userland.  Nouveau will do the
same thing.  Via will also use the TTM backend, though I'm not certain
how it will present to userland.  I still haven't managed to get my
hands on any VIA hardware, so I'm a bit out of the loop there.

As far as KMS goes, I anticipate much of the code for
Intel/Radeon/Nouveau to be fairly portable.  The tricky part is figuring
out how to hook it into our console rendering code, which I still don't
fully understand.  We will also need to figure out how to handle
hardware that we don't have KMS support for.
