System: 20" intel iMac w/ATI Mobility Radeon X1600 and Dell E196FP analog external monitor

I can't seem to get big desktop (spanned desktop) running. I am able to get dual screen (two independent screens) working, Can anyone look at my xorg.conf and tell me what changes to make to get big desktop working? I would really appreciate it.
