yes this feature is supported and there are many variations to
accomplish that.  There's "regular" dualhead and mergedfb.  with
"regular" dualhead the driver loads twice, once for each head and
video ram is divided into two framebuffers, one for each head. With
regular dualhead you can either run two independant heads :0.0 and
:0.1or as one big desktop using the xinerama option.  Mergedfb has two
heads looking into the same big framebuffer, so it's all one big
desktop (like xinerama).

See my dualhead page for more info on dualhead support in xorg.
