Interesting.  I'll have to try that in my startup script.  I have that
rmmod && modprobe twice in there, but it still doesn't always work.

That rings a bell.  I think I usually need to unload cx88_alsa and
cx88_dvb as well.

You'll have to report back the results.  I know the HVR3000 developer
Steve Toth follows this list.  I'm sure I've tried in the past messing
around with module options, but it still seemed random to me whether it
detected the tuner or not.
