I have not done that, but as far as I remember it is possible.
This is roughly how it is likely to work:
You will have two display environment variable settings, let's say
DISPLAY=:0.0
in one shell and
DISPLAY=:1.0
(or was it :0.0 and :0.1? :)
in another.
Then you will have not only to start the usual XServer at :0.0
but a second one for the :0.1 display.
Let's try it for fun with one graphics card:
X :1 &
You should now run a second X server.
On this box here I can switch with Alt-F7 and Alt-F8 between both X11
servers (the exact keys depend on your /etc/ttys or so terminal settings
file)
Now on the old display hack this into a sh or bash shell
export DISPLAY=:1
xterm
This means you route all X11 output from that session to the
new display 1 and then open an xterm there.
Switch to your new X server and you will have a xterm there.
What you now need to achieve is to start/assign the two servers
to the two cards, instead of one.
This should be possible by some command line option.
I assume also that you might define a second card
and eventually a second monitor in your XF86config.
Anyway, it is likely that one of the guys here with a
running two or three card configiration (Greg?) will answer
this for you..

Marc
