Chimera supports stereo using workstation graphics cards, i.e., NVidia 
Quadro FX and ATI/AMD FireGL cards.  We don't have a recent FireGL card 
(and driver), so the rest of this email will be about the NVidia Quadro FX 
cards and driver.

The Quadro FX graphics cards have two video outputs and the driver lets 
you display the left eye on one output and the right eye on the other. 
The higher end cards have SLI support (on FireGL it's called CrossFire) 
which lets you use two matched graphics cards together.  It is unclear to 
me how or if SLI/CrossFire and stereo work together, but I would expect 
them to.
