Huh, that's interesting. I took a look at that file, and it mentioned 
TwinView. That surprised me, because although I had tried TwinView a 
couple times, I had given up on it and keep trying to configure TV-0 to 
use a separate X screen instead.

So I re-ran nvidia-settings, configured TV-0 to use a separate X screen 
(since the configuration is always reset when I restart X), and told the 
app to write the new config out to /etc/X11/xorg.conf. Then I took a 
look at that file. I see, among other things, lots of references to 
TwinView (see below), which I would not have expected to be there.

Should I be concluding that nvidia-settings isn't properly generating 
the xorg.conf that I expect? Maybe all this is moot and I should be 
trying to write xorg.conf myself as we've already discussed, but I 
thought I'd send this on and see if anyone has any insights. Selection 
from xorg.conf generated by nvidia-settings is below:
