If I understand your question, No.

it sounds like a faulty card, or it isn't seated, or something of bad hardware.

pull it out, run lspci >lspci.1.txt
add it back, lspci >lspci.2.txt

diff lspci.1.txtlspci.2.txt

If you don't see a new entry... um... you don't have a card ;)

if you do see a 2nd firewire card, you should see
/dev/fw0
/dev/fw1

and when you plug in your dv camera to either card:
/dev/fw2
