I can report partial good news.  I installed kernel 4.11 from backports
on a test machine running stretch and one tuner became visible (one
green led on the tuner).  Mythtv-setup (0.28 from deb-multimedia) after
proper configuration, detected 60 channels after a channel scan.
Unfortunately, that computer has issues with the display (possibly
config issues) so using myth there is not possible until I track that

Next, I decided to install the sources for kernel 3.16 on the myth
box that's running jessie, and apply the patch.

The excellent instructions here made it easy:

Since the above didn't work, I'm now upgrading the myth machine to
stretch.  After changing all "jessie" to "stretch" in /etc/apt/soures.list:

apt-get update
apt-get dist-upgrade.

Then I'll install the backports kernel 4.11 and I'll have at least one

Does anyone know what Debian kernel has the 2-tuner patch/addition?
