First of all, thanks so much for the response!

So, it appears to be recognized as a 950Q and load the firmware correctly.

After playing around a little more, I found out that it does seem to
tune analog cable with TVTime, although no sound plays. I set it back up
in Myth, and it's able to tune the default channel with an AUDIO
DISABLED warning; as soon as I try to change the channel, mythfrontend
locks up with a bunch of these in the log file.

From mythfrontend.log:

RingBuf(/var/lib/mythtv/livetv/1007_20160109191051.nuv): Taking too long
to be allowed to read..
