Here's a placemarker -- it would be nice if someone would fill in some steps people can take here.

With a previously unsupported card, you'll have to figure out what inputs connect to what channels on the chips, and thus come up with a new card definition dataset to put into the appropriate driver -- bttv, cx88, or sa7134.

What information do I need to provide in order to help get some support for a new card?

lspci -vvxxx would be a start; from this information we'll be able to see whether the bttv driver can be taught to autodetect the card.

Then, to make a proper description dataset for the card, you'll need to figure out where each of your camera plugs connect (as in: which pin on which chip).
