There is as far as i now no limitation on how many cards you can have.

That is not nasesary. I'm writing this on FreeBSD with a ATI and a Matrox
card.
The only requerment is that only the primary video card may post. It's usualy
a jumper you have to move.

From my XF86Config

Section "Device"
    Identifier  "Matrox"
    Driver      "mga"
    BusID       "PCI:0:18:0"
EndSection

Section "Device"
    Identifier  "ATI"
    Driver      "ati"
    BusID       "PCI:1:0:0"
EndSection
