Ok, I've set up dual monitors with the propriety ATI driver under gentoo using mergedfb. It worked, but it's behaving like just one big monitor, instead of two separate ones, like I've had before inubuntu. Like, a maximized window will take up both monitors, instead of just one.
Heres a copy of my xorg.conf
