I've almost done this already, although a few still remain.

mmap() is the right way to go, and you don't need to play namespace
games. I've built the protocol to make this easy to add, even if it's
quite evil; I can sketch out how to go about it if you're interested.

There are a couple of tricky prerequisites for this. The nastiest one
is probably font handling. I think all the others are taken care of
now (although you'd have to work from my branch to get current YKB
support).

An Xv clone, I'd say. That's closest to what they want to use.

Their drivers suck. You will regret this. You have been warned.

Frankly I'd rather get hold of the hardware documentation and do it
from scratch.

Excuse me while I vomit. All the existing free GL implementations are
vile devilspawn. They're even worse than xfree86 drivers.
