With this patch radio works perfectly here (PAL card tested, NTSC card should work too).
Note1:
There is currrently a race condition left.
When you don't get these two lines:
kernel: bttv tuner received pinnacle id 2
kernel: bttv tda9887 received pinnacle id 2
report this fact (and workaround by "rmmod bttv; insmod bttv").
Note2:
Patch is against http://bytesex.org/snapshot/
Hopefully Gerd will make 104 soon.
