Theres no way its impossible. I just pulled off the craziest wide screen action on Oblvion today. I had it stretched across two monitors (2560 by 1024). Amazingly enough Oblivion actually supports this! (So does World of Warcraft).
To get this functional I realy need to get monitors with a slimmer edge, or try to get a third monitor in the mix so the screen isn't split right in the middle.
Strangly enough oblivion still ran at 25-35 FPS... The screen shots don't show this as when I took them the computer chunked up and lost at least 10FPS by the time the screen shot was done. (They were 8 megabyte BMPs).
So here's the screens if anyones currious:

My computer specs are:
Asus A8N-SLI
Corsair 512 MB x 2 Dual Syncronized Ram
AMD Athlon 64 3000+
Asus Nvidia 7600 GT 256 DDR3
As you can see my specs are relatively low and it was very playable even with the entire town guard chasing me.
