Thanks, Ryan, for the reply.

After a bit more work and research, think I'm getting closer and a 
little smarter ;-)

The applications running on the remote machine need to display to the 
local monitors and not back to the remote.  Not sure if I made that 
clear in my initial query, just wanted to be sure we are "on the same page"

Part of the problem is that I can't get the server(s) to run on both 
cards. In the Xserver file there are two entries

:0 local /usr/X11R6/bin/X :0 -layout TwinView
:1 local /usr/X11R6/bin/X :1 -layout PCI_CARD

and either can be started with   linux$ startx -- -layout <name> but not 
both.  The XF86Config file seems to be okay, in that when either display 
is started it comes up on the correct card with the proper monitor.  
Would seem to indicate that the layout, screen, and device sections of 
the config file are okay.

Something is missing, misconfigure, or both..  I'll keep digging and 
learning ;-)
Thanks again
John W.
