They will work on Quadro cards.  Make sure Option "Stereo" "1" is in 
XFree86Config (and see nvidia's readme for details)  I'm not sure if there 
are software geforce to quadro hacks for Linux.  Performance should be 
roughly half that of non stereo, for all modes.

Also, try turning on Vertex Arrays in System & OpenGL - it uses vertex buffer 
objects, and try turning off shadows in the scene buttons.

I don't actually have access to any shutter glasses, but I have had a report 
that it works!

That was supposed to be fixed 10/8.  The display lists are caching the 
lighting passes, where textures are disabled.

I don't think it's anything to worry about - lights & cameras don't seem clean 
up after themselves, so they are deleted in the sumo scene.
