I guessed the clock settings based on how the same tuner is used by a
different demod. The deltaf value was found by trial and error (helped
by some scripting). deltaf values slightly off will also work, but
tuning will be very slow. I also think the deltaf value will depend on
the bandwidth of the transponder tuned. All transponders I've tested
with are 8MHz, but I think other values are possible, and these will
most likely not work. I submitted the patch anyway in the hope that some
broader testing might help uncover any remaining problems.

I was trying to follow the guidelines, but I guess I wasn't doing that
good enough. Will try to clean that up and resend soon.
