E. Enabling The FM Radio for Radio-Equipped Cards
FM radio tuners are easily enabled when inserting modules. Simply
...or add a similar option to your 
/etc/modules.conf 
and you should be set the next time you restart or load the module. You will 
also need an application to access the radio. I suggest the 
console based 
radio, available with the 
Xawtv suite, or 
fmtools. 
For graphical programs, try 
gnomeradio 
or 
gradio or 
xmms 
with the 
FMRadio plug-in.
Also, you can't listen to radio at the same time as watching TV with your Bttv 
card (unless you have more than one card, that is).
