There are probably a fair number of TV cards in both ISA and PCI wandering about, since they're not terribly useful with the advent of digital TV (and the web). Has anyone hooked up an ordinary NTSC modulator with one of those and an 8 bit PC that relies on the peculiarities of NTSC chroma

The output of a single-chip tuner might also be at IF. The Maxim part (which I will not use) outputs at 36 MHz, I think. Can't tell the output of the SiLabs part without more info. Hopefully it's either baseband or a lower IF 36MHz does sound like the standard TV IF frequency.
