I run double headed.  I run a single server with two screens (:0.0 and
:0.1).  This way both screens share the mouse and keyboard.  When the
mouse hits the side of one screen, it switches to the other screen.  The
setup works very nicely.

If you tried to run multiple X servers you would have a problem
attaching a mouse and keyboard to the second one.  Can you have two
keyboards and two mice on the HIL bus??  I don't believe this Xserver
supports serial mice, though that wouldn't be hard to add to a source
build.  But I wouldn't recommend any of this.

Once you get the hardware and the kernel to recognize two graphics
cards, you will need to get a new X server.  The one on ftp.netbsd.org
has a bug that prevents the second display from working.  I can give you
a new binary (the only difference is this second screen business).

Let me know if you have any questions
