because there is a difference between xinerama and dualhead:
* xinerama accumulates 2 or more monitors as one big screen
(simplified, the concept has some quirks)
* dualhead makes 2 or more monitors independent screens.
Generally I like dualhead setups more, but that is matter of personal
preference, and what software one wants to use. Some programs and
windowmanagers are notoriously known for breaking on xinerama.
It also depends somewhat on the hardware you have, some (lower) end
graphics boards can use xv or opengl only on one screen or xinerama
screens give a big performance bottleneck because of the high res.

Some allow a third device and route that out on a S-Video socket, that
was my intention, use that for a reference TV compatible signal, I just
didn't played to figure out a suitable pal-compatible modeline yet.
