Thanks for all the suggestions!

I did try plugging the LCD back in, actually, but the monitor insisted 
that it had no signal when I did. So far as I can tell, my video card 
really wants to output to one or the other. I can't figure out how to 
tell it to output to both.

When I run nvidia-settings (after rebooting with the LCD plugged in so I 
have a decent monitor to use!), I see two displays in the layout: my LCD 
(HP L1906) and TV-0. TV-0 is labelled "disabled." I configure TV-0 so 
that it is enabled, save to xorg.conf (with a backup made first!) and 
restart X (with the TV turned on). When X comes back up and I run 
nvidia-settings again, TV-0 has been turned to "disabled" again.

I am flummoxed as to why TV-0 gets disabled. I recognize that it may be 
time to tweak xorg.conf directly, but have no idea where to start with 
that -- any suggestions would be very welcome.
