It doesn't look like it shows up as a PCI device, but I figured out what
it is. I noticed this in my XFree86 log file:
(--) NVIDIA(0): Detected TV Encoder: Philips 7108
That apparently does both TV-out (which is why XF86 had something to say
about it) and TV-in. I found a Linux driver at
http://rivatv.sourceforge.net/. I wonder how hard it would be to port
this...
