I was under the impression that all of this had been taken care
of years ago when SGI and NVidia settled their patent infringement
suit.  NVidia got the rights to use a lot of SGI's stuff after that
in addition to getting a lot of SGI engineers.  (SGI got, well, I'm
not sure I want to go there...).

SGI has been fairly proactive about open sourcing most everything
they can.   When I was there, several years ago, I was told they
were going through all the code they had looking for stuff they
could open source.  Pretty much the only stuff they weren't opening
was stuff that was tied up in licenses and some other stuff which
they actually made money on (Performer comes to mind).
