We have cyberblade docs. We have enough info to do a bad older Nvidia
(enough to be useful for 2D use of 3D). We have Cirrus docs, we have
siliconmotion (I think), we have S3.

3DLabs have provided some docs to people in the past so may not be
intractible. i740 might be fun though 8(

As regards performance, (with the exception I'm told of the Nvidia
binary driver) all the XAA drivers suck at reading data back from the
screen already so Mesa wont make it worse.
