Well, if you were using xdm as the display manager, you could edit
/etc/X11/xdm/Xservers and change

:0 local /usr/bin/X :0

to

:1 local /usr/bin/X :1

I do not know it kdm or gdm uses that config file, or have their
own. I know they did use it way back when I needed to add an extra X
server or two. But I have not worked with this lately. I am sure
there are tools to configure them now. Someone else here is sure to
know, and post the info...

That has been the problem I've been running into with newer versions of Fedora.  Xorg and company have been moving towards a "work out of the box" philosophy and have done away with a lot of the config files in favor of dynamically generating these so things just work, and a simple hardware change does not break the OS as often.  I've been trying to find where Xorg is actually run, so I can get it to run the way I want. 

Now that I have played with Xephyr a little bit, I have found that I actually prefer this configuration for the way we are using these computers, as opposed to just starting X with no window manager or just querying a remote host.

Thanks for all the help so far.
