There's a whole bunch of stuff that looks like it would be specific to SUSE or some other stuff you're running in that conf file, I've just finished messing around with some x.org conf stuff for TwinView and/or Xinerama and 60% of that file you posted looks like nothing I've seen before (or that you would require to acheive what you want).
can you post your working config, and perhaps I can use this as a starting point???
