Linus,
The SGI vis workstation support has been unmaintained for moons.
I've even heard comments that it currently doesn't work.
Patch below removes it from generic x86 setup, so it can bitrot
somewhere else. If no-one steps up to maintain this by the time
we reach 2.6.0pre, I vote for dropping it altogether.
Dave.
