It's resolved itself. You know how you make one big circle and come back
to where you started and everything works when it didnt before.

I put the card in, installed the kmod-fglrx driver and rebooted the
machine into runlevel 5.  Nada.  Black screen. Looked through the
Xorg.log files and wrote to the list.

Then, I decided to try the vendor's driver. Removed the kmod-fglrx
driver and rebooted the machine and the gui came up. At the full
resolution of the screen.
