KDM ignores changes made to kdmrc (EDIT)

I'm sorry for this probably stupid question, but any changes I make to usr/share/config/kdm/kdmrc are "ignored" when I restart the KDM daemon. I've tried disabling the shutdown option, changing the logo to clock, etc. I have used both vi and nano and have confirmed that the changes are actually saved in the file. This is all done via root and I am shutting down KDM prior to editing kdmrc. I have not used the Login Manager Systems Settings Module in KDE (and the kdmrc contains all the comments). The AutoRescan key is commented out, but if I uncomment it to True, the problem remains.

kdm.log contains three Font Invalid Description entries and that's it.

errors.log contains

Aug 21 18:34:14 SUGAREE kdm_greet[3861]: Cannot load /usr/share/apps/kdm/faces/.default.face: No such file or directory

I didn't have a faces folder, so I created one with a .face file in it, and the error went away, but the problem remained. Please help!

EDIT:
After spending a few hours with the problem I posted above, I've realized that the main problem is with how I am configuring kdmrc. KDM's behavior does change if I alter certain keys, just not the ones I mentioned above.

I have two physical displays, an LCD and a plasma TV, connected to a hybrid desktop / mythtv HTPC. Ultimately after boot I want KDM to appear on display #1 (the LCD) and the mythfrontend to automatically start on display #2 (the plasma). I have configured xorg.conf for two separate X servers. As of now, if I boot to console and log in, I get tty prompts on the LCD and nothing appears on the plasma. If I start KDM or XDM from tty1-6, the appropriate GUI will start on tty7 or tty8, and I can move the mouse onto the plasma, where it appears just as an X on a black background. From there, DISPLAY=:0.1 mythfrontend in a console will start myth on the plasma.

What I would like is to have myth start without having to enter this code in a console or even having to log into KDM. But, I can't seem to get KDM to do anything with the second screen. I tried designating 2 static servers in kdmrc, but they appear in tty7 and tty8, both of which are on the same screen. I also configured bashrc to run startx and xinitrc to run mythfrontend for the mythtv user to automatically start mythfrontend / x from the console after login, hoping that KDM could automatically log the mythtv user into screen #2. But, it only works on the LCD screen and not the plasma screen, since I can't get tty's there.

Here's xorg.conf:

If anyone has advice on how to achieve this setup, I would be appreciative, even if it means scratch this whole approach and try something different.
