Replying to myself:
After playing with things for a while, I've noticed that the sound seems
a bit high-pitched and it seems to skip every second or so in mythtv
(this doesn't start happening, apparently, until after I run
mythfrontend the first time).
This even seems to happen when just copying from /dev/video0
to /dev/video16
(prior to running mythfrontend, everything seems to be fine)
my ivtv dmesg output during module loading looks like:

and after loading the ivtv-fb module I get:

I'm not sure what's going on, but I feel like I'm close!
Thanks,
