[xmonad] Multi Head Setups with Newer Xorg?

Hi All, Since upgrading my ubuntu install (and breaking my multi head xmonad setup), I've been reading a lot about how xinerama is broken for newer xorgs, and is deprecated in favor of xrandr (which doesn't handle multi-head on more than one card). Looks like my only option is to revert back to ubuntu 8.04, or dump some screens. How are you dealing with this? Has anyone found a workaround? -matt
