The XFree86/Xorg server is able to run using several video cards but 
with only one pointer/keyboard. A module called RAC (Resource Access 
Control) prevents conflicts beetween the video cards, allowing a server 
with several cards from different manufacturers to be used.

Using the the multiXnest server, we can take advantage o the 
XFree86/Xorg RAC in a multiseat environment. Today, we have three 
different hardware configurations stable:

- 4 seats with 1 Radeon Dual 7000/VE AGP + 1 Radeon Dual 7000/VE PCI
- 4 seats with 1 Rage 128 + 3 Rage XL
- 4 seats with 4 SiS 315

It should work with dual nvidias and any other combination that works 
with an ordnary xinerama x server configuration.
