I have a number of different dual-head setups running.  If you choose a
dual-head video card (like the Matrox G450), there are usually multiple
ways to do it.  The G450 driver can treat the two heads as a single
screen (so the X server thinks there's just one big screen), or you can
set them up as separate screens, then have xinerama combine them back
together (which has some advantages).

Cheers!
