Multi-head displays are supported under X. I have personally used matrox and nvidia cards in dual and triple displays. It all depends on the driver support for dual display. Both matrox and nvidia support multi-head displays. check out the nvidia site, they have a sample Xfree86config file that demonstrates how to setup 2 separate Graphic cards on the same machine. I am no linux expert but it has something to do with defining which PCI/AGP bus address is used by the respective cards. Each card will run a desktop or you can even club the desktops together to make a large desktop. I have tried it with the Matrox G450 DH and a Matrox G400 PCI to get 3 monitor displays and on another occasion with a Gf4 Ti-4200 and a GF2 MX PCI to get 3 displays.
