After more investigating:

I can make the tuner work again by requesting a very high frequency like
2000 MHz and then the frequency I want (using radioctl).

I can also make the tuner work by starting xmradio.  It _always_ fixes the
problem immediately.

I added some debug printf's in the driver, but as far as I can tell, the
parameters passed to the FR1216 tuner (when changing the frequency) are
always correct.  I made a small change in the radio frequency setting
code after reading the Philips datasheet (effectively copied some code
from the TV side), but this didn't fix the problem.

I noticed that xmradio uses /dev/tuner instead of /dev/radio.  However,
I seem to have no manual page for /dev/tuner, so I can't easily write
a test program to see if I could make it work as well as xmradio does.
