Just to clarify: I do get the standard text readout when the PC boots 
and Linux boots -- -on both displays.
Yeah
But, when it goes to a higher resolution display (x may have started, 
but I don't think so.. I'm using FC2) the TV display goes white.

I tried changing my computer monitor to 640x  and 800x and restarted X, 
just to see if I need to have the displays the same resolution, but that 
didn't change anything.  I've been googling for answers to this, but 
it's strange that I haven't found anything. (I did find a HOWTO that 
someone put together, but he's xorg file is configrued differently. see
