The MergedXinerama option (which you have enabled in the config excerpt
above) should be getting you the Xinerama hints necessary for your WM,
if your WM knows about xinerama.  I didn't think you wanted the 2nd
device section in this case of using MergedFB, but that would be my only
suggestion.  I haven't run any multihead system personally, and I know
it's tricky from the one I've ever set up.
