You might want to look into something called SoftTH. It's like a software version of eyefinity that works with any video card (even Nvidias), or like a software version of triplehead2go. It works by using 1 card for rendering. Most cards only have 2 monitor connections, so you need another connection--even the integrated video card on your motherboard will work, as it is just sending the info through it, not using it for rendering. I'm running a 5760x1080 setup myself--3 24" 1920x1080 monitors. I'm using an ATI 4890, which doesn't support eyefinity--but with softTH, I can play with triple monitors. Anyway, might be easier to play with because it is a software solution to multi-monitor or strange resolutions. Oh, and i'll second the multiple cameras--from lurking around other softTH and multi-monitor things, that's a good way to go to remove any fish-eye or HUD stretching. Basically, you leave the center camera alone with the HUD, and add cameras which are at say 45 degrees for the side monitors (like side view mirrors in a racing game, except pointed forward). I really don't know how possible this is with the tools you have available, but I believe that is how it's done. It's likely easier to add some kind of FOV tool to calculate what the user should plug in based on their resolution, but this doesn't correct the HUD being stretched over 3 monitors.
