Here is the modules.conf setup for the card.   I have this card and it 
works great under linux.   You have
to setup the tuner properly.   At first the sound will not work unless 
you override the gpiomask values.

options bttv    pll=1 radio=1 card=22 gpiomask=0x000000FF audiomux=0x1,0x0,0x4,0x2,0x8
options tuner   type=2
