Ok, I found the cause of the oops. Some of radio tuner code was
expecting a struct bttv_fh to be allocated but this wasn't done in
radio_open. So it would dereference an invalid data structure, causing
a hang for me and an oops for Bongani. I also had to add support for
the radio tuner to some shared functions. Patches to follow.
