I got an email from the X team today which told me that pulic release date for
a beta snapshot of 4.0 still is set to June.

That 8514 driver is certainly a good driver to look at while writing a driver
for the SGI cards, but it's generally a bad idea to just rip the code off. I
have at least not had much luck doing success hacks.

The 8514 driver is also a quite old driver and it's not using the new interfaces
in for Xserver.

The copyright still remains to the person who wrote the code, and even if the
code is locked away in a beta release, it's possible for the writer himself to
make his own code public (i think).
