No, actually I didn't, I thought is was enabled by default, so I must admit
I overlooked it in the driver instructions. I have to add the line
Option "Stereo" "1"
to the XF86Config file. That's a pity - the FX1000 is probably faster than
the 750XGL :-) Well - the supplier accidentially swapped my and
another costumer's orders - so I was honest and sent it back :-)
Also, even with the cheap GeForce 4MX card currently in the machine, the
(mono) graphic performance is incredible - I guess it's an order of
magnitude faster than the VPro6 graphics on our SGIs :-)
Cheers,
Esben

Esben,
Are you sure you correctly configured the nVidia driver
(XF86Config) for Stereo? It's not automatic, but as AFAIK, all the FX's
are QBS capable.
Cheers,
Warren
