Please disregard that last email. I did not do #2 correctly. I moved  
the files in /usr/share/X11/xorg.conf.d/*.conf

When I returned them and booted without any  
/etc/X11/xorg.conf.d/xorg.conf file, The two displays came up nicely.

Thanks, Felix for helping me out. The card was cheap enough. Having  
two monitors going is really nice.
