When I startx with 6.9 and an xorg.conf file that supports xinerama on the
same hardware with 6.8.2, I'm pretty sure that X is putting out the correct
sized image (width = internal 1024 + external 1280), but the monitor reports
that it isn't receiving a signal.  Moreover, with xinerama disabled, I can't
convince the external monitor to receive anything other than a 1024x768
signal, even though it is 1280x1024.
