Well, I might have figured it out first, since I added the modprobe
option to the driver.  :-)

That indeed sounds like breakage in MythTV.  None of that stuff has
changed in the driver in quite some time.

Sounds like somebody is going to have to break out a debugger and see
what is going on.  I haven't done a debug compile of MythTV since I
built 0.22 to get analog working with the 950Q in the first place.
