TV-Out does work for some cards to some degree with the driver, and it
also works for the old i810 chipset (which is fully documented) with
extra programs.

The open 'nv' can use tv-out with an extra program.

AFAIK, ATI cards can also use tv-out with help of an extra program.

You just buy one of those cards, and use the extra programs.

The problem is that (a) X doesn't contain the infrastructure to handle
the extra values needed to program the TV encoders, which is why every
(proprietary) driver cooks up its own set of options to handle TV in a
somewhat limited way, and (b) graphic card manufacturers don't publish
their specifications. Complain to the manufacturers.
