That's crap, the community did step up, the Weather Channel paid for
the r200 drivers we have now, ATI's register information was far short
of complete, I have the full stack of it here and it doesn't allow a
proper implementation of any of the "cool" features, i.e. hyper-z,
programmable hardware, so how could open source driver be as good if
they info they give is substandard.....  to be honest if a company
wants to do open source drivers for their cards they should support
it, with people, they didn't try at all,

they can try and hide behind it was the communitys fault all they
want, but it's crap I'd rather you didn't spread around here....

and the difference is?? their current 3D closed source drivers are
crap they know it, the community knows it, if they had open sourced a
completed driver 6-8mths ago, it would now work with X 6.8.1, Linux
2.6.9, powerpc, x86-64 and may even support doom3, and they wouldn't
have to had done anything for that, these big companies have to meet
the community half way, give us a complete working x86 driver for an
up-to-date X and someone will probably be interested in keeping it
running until the end of time... look at the (r300.sf.net to see how
much effort some people are willing to put into reverse engineering
the r300 3d parts...)

ATI and Nvidia not open-sourcing 3D stuff for one simple reason, IP
issues. It is also why Intel are not even giving out their later
chipsets docs to anyone by Tungsten, if anyone tells you differently
send them to me :-)
