XFree86 4.0 supports this, both dual head from a single video card
with multiple outputs (such as the G400) or from two separate video
cards. Check http://xfree86.org/ for details and downloads. NB. these
are new features in XFree86 4.0, previous versions (as shipped with
most current Linux distributions) did not have them.

A related tool is x2x, which allows you to control an X session using
the mouse and keyboard from another machine. Essentially you get the
same kind of interaction as above (one set of mouse+keyboard, multiple
monitors, and you can move the mouse between them seamlessly) but each 
monitor happens to be the display of a different machine. I have
this set up at home between 3 machines (2 Intel, one Alpha) and it's
very nice to use. You can even select and paste between machines
with the middle mouse button ;) x2x is available from
ftp://gatekeeper.dec.com/pub/DEC/SRC/x2x/
