If need be, I can send you an xorg.conf where I worked out how to 
configure twin view as two separate X11 displays, rather than a single 
big display stretched across two monitors.  It's not that hard to do, 
but the nvidia README.txt didn't directly explain it so I had to puzzle 
out a few of the pieces.

That would let you run two separate copies of FG to the two separate 
displays and you could add in the dead space between views quite easily.

I don't know the performance implications on doing that though ...
