Xrandr not supporting old resolution

Upgrading Xorg completely broke my system. Lots of not-fun later, I found out that setting up dual-head has to be done with xrandr, which seems like a good way to do it.

However, xrandr does not support setting the resolution from before...
I want to have my two screens running at 1280x1024 (which is quite normal I think, anyone having two 19''ers ).
Now xrandr tells me, that the maximum resolution I can use is 1920x1200. Perviously with xinerama I could set the resolution to 2560x1024 without any problems.

Anyone have similar problems? Anyone have a solution?

xrandr -q:

This is the only screen running right now, the one I wish to extend using xrandr...
