To support direct rendering you need applications to:

1. Have access to the hardware acceleration registers.
2. Provide context switching (which the quoted video card
does).
3. Implement the kernel communication channel.

(2) and (3) are trivial with the proper hardware. How do you deal
with having your regular application get access to the io ports of the
video hardware without granting root?

Cheers,
Miguel.
