My bad. The problem was that I copied some old bttv options to the bttv2
line in my modules.conf when I installed bttv2.
I had:
options bttv2 card=10 radio=1
It should have just been:
options bttv2 card=10
because the "radio=1" option sets the radio minor device number to 1 for
the first card, but it should be 64, so the second card fails when it
tries to grab minor device 1 for its capture. To use radio devices on
both cards, "radio=64,65" would do the trick.
Sorry for the noise.
