Ah! So the monitors work, but Xinerama doesn't? Hmm. Well, I think 
you have the right stuff in 

  Section "ServerLayout"
  ...
  Screen      0  "Screen[0]" 0 0
  Screen      1  "Screen[1]" RightOf "Screen[0]"
  EndSection

My layout was a bit simpler; it was just

  Screen          "Default Screen"
  Screen          "Other Screen" RightOf "Default Screen"

..and that seemed to work. I don't know what those 0s and 1s do.

How are you starting X? From a virtual console, with "startx"?
Or with a display manager? (xdm, kdm, gdm) You need to tell the
display manager about Xinerama. I know how to do that for gdm,
but I suspect that SuSE uses kdm, which is different. 

And if you are starting X from a virtual console, you need to 
mention Xinerama there, too. Something like this:

startx -- +xinerama
