Well, it gets curiouser.  I worked a bit harder at removing the kernel's
built in drivers and put in a hand built 0.2 and then 0.4.4 version of
ivtv (did not do 0.4.5 because I wanted to change things.)

I eventually got past the tuner not being identified, and the system is
working now -- except I am getting the classic "cable channels off by one"
problem, ie. channel 64 shows up when you tune to 63.  (But 5 shows up on
5.)  This problem is normally identified with tuner mis-identification, but
it's always been identifying it as a 50, and after it started working it
still does so, and I haven't seen any indication this model would be other
than that.   Is there a nice directory of other tuner numbers to try?
