Here is a patch that should let you do:
v4l2 -v 2 setfrequency 196.250
and get BBC (well, if you live here....).
I *DO NOT* guarantee that this does everything correctly.
I just hacked the set_station section (or was it the
set_channel section?) to change the channel. I didn't
even check the audio to see if that worked after.
Use at your own risk.
