I have a 7200 lying about somewhere.  I may just see what happens with
it.  I originally bought it b/c it had a component dongle and I wanted
to see if using component-out had the same sync problems that DVI has
(it does, even though I can use the built-in 1920x1080 modeline and not
a custom modeline).

I can say for certain that the mythtv-vid branch does not resolve the
problem.  I tried it with my card (Nvidia 6200TC) and it exhibited the
same problems described above.
