Sometimes, you can 'guess' this by working from the AGP/PCIe x16 part
to the edge of the board - the lowest adapter# is the one nearest the
video slot. You may also be able to wrok this out using the dmesg log,
the udev log, and lspci - the 2 tuners on the same card will likely
have the same tuner information associated with them (and lspci
output) making it easier to identify the dual tuner.

If they're all DVB cards however, as long as the modules are loaded
and the devices created properly, you don't need to worry which is
which (unless one card is better than the other so you want to give it
priority).
