I attempted what you are doing once. My monitor had burned out and I had a
TV output on my video card.
Magically, Win2k somehow set the video card correctly for a monitor.
When I would attempt to boot RedHat, the text console would work fine (as
did the BIOS and everything else).
But when it came time to start X Windows, all I got was gibberish on the TV.
I have found a few posts on the internet for people in Europe displaying
XWindows on their TV, but none for NTSC (us) TV's.
In the XF86Config file (or XF86Config-4), there is a "clocks" line that
specifies what clock settings the dot clock in the graphics card should use.
I found the following site while searching for info on your question:
http://yebisu.ics.es.osaka-u.ac.jp/linux/HOWTO/XFree86-HOWTO-5.html
http://www.tldp.org/HOWTO/XFree86-Video-Timings-HOWTO/synth.html
With only your TV plugged into your video card, try running X -probeonly and
see if it is able to find anything....
If not, and you can dig up an average viewable and actual number of pixels
on a TV, you could make your own entry in XF86Config and it should work with
your TV (provided your video card can support that rate). The dot clock
should be the product of the 60 (60Hz refresh rate) times the number of
horizontal and vertical pixels (including the non-displayable ones).
Let me know if you get it yours working.... I haven't been able to find a
good page that documents someone hooking their Linux box to a TV.
