Is it possible with an EyeFinity enabled card to make multiple display groups at once? I was playing with a FirePro 2460 and while a 4x1 or 2x2 display group works quite nicely, if I make a 2x1 display group and then select one of the other displays to try to make a second 2x1 display group, it disables the first one. Is there any way to circumvent this behavior and set up two separate spans on the same card?

Additionally, can you set up distinct display groups if they're on different cards? I will have the opportunity to test several of these cards in one machine very shortly, but I'm curious if anyone has any experience. EDIT: I can confirm that you can make multiple spans on multiple cards (as long as they don't cross cards, obviously)

(If the answers are different for FirePro/FireMV cards and Radeon cards, that is helpful and relevant knowledge - I doubt it, though.)
