Xinerama can handle multiple screens of any resolution - the
resolutions don't have to match.

The configuration looks good to me. I suspect it would be a driver
limitation of some kind. Not all drivers support Xinerama properly.

Does the Xorg log file give any hints? I know the nVidia driver quite
happily tells you in the log when it can't do things (ie: 'NVIIDIA(0):
such and such enabled: disabling something else you want').
