Switching those two lines seems to improve the dependencies for my setup.
However, audio still does not work. Furthermore, switching channels in
tvtime now hangs for up to 5 seconds. strace -r shows that it spends a lot
of time in the second ioctl.

0.000085 ioctl(4, VIDIOC_G_TUNER, 0xbfef1d70) = 0
0.000385 select(5, [4], NULL, NULL, {3, 0}) = 1 (in [4], left {2, 988069})
0.012006 ioctl(4, VIDIOC_DQBUF, 0xbfef1dc4) = 0

The current dmesg output is as follows:
