What's the difference between a single large desktop and two separate
desktops, if you can drag windows between them?  Separate workspace
switching?  I'm afraid I don't know of any window manager that would
support that.

This kind of old-style static multi-screen configuration is no longer
supported.  See http://intellinuxgraphics.org/dualhead.html for details
about the new configuration options.

I'd suggest going back to the original xorg.conf and adding just a
single tweak to it: in section "Screen", add a SubSection "Display",
with a Virtual line specifying the largest total desktop size (summed
over all monitors) that you're going to use.  Then you can use xrandr
from the command line or, e.g., GNOME's Screen Resolution applet to drag
your monitors around to a desired configuration.

HTH,
