The thing I'm trying to is is setup a kind of radio-recorder. Which can 
be programmed (webinterface or whatever) to record radioshows and switch 
to the correct radio-channel. So simply connecting an normal radio to 
line-in wouldn't work unfortunately in this scenario.

I received three mails with suggestions to patch conf.c to add the 
necessary major device numbers for dev/bktr and dev/radio. I chose 
numbers 63 and 64 cause these are the next free and unused in macppc.

This does the trick! Now i can use the tuner. Use it in some way.

bash-2.05# /usr/bin/radioctl -a
volume=0
frequency=83.50MHz
mute=on
stereo=off
card capabilities: stereo detect, hardware AFC

A Speaker connected to the cards line-out gives some noise. It's 
possible to mute and unmute volume. The new problem i ran into is: even 
if radiocl is able to switch frequency (or at last it says it is 
switching frequency) I'm not able to tune in a channel and get some 
useful audio on line out. All I get is noise. One crasy thing. I can't 
change the volume setting. It remains 0 whatever I try, but even then 
the card gives some noise on line out.

Right no I'm not shure if my fm-tuner is broken or if it's still a 
driver related problem.

You can find the modified kernel, MAKEDEV and conf.c on

Please let me know if you're able to get some music out of a radio card.
