^^^^^^^^^^^^^^^^^^^^^^^^
/usr/src/sys/dev/bktr/bktr_card.c has some interesting comments about (some?)
bt878 based cards that have an EEPROM. In short: they've been broken by the
time MT2032 tuner support was added, and they're still broken. I've had
similar problems with an (old) WinCast TV card; it stopped working somewhere
around FreeBSD-5.3 or so, also because tuner detection fails and it can't be
bullied into using the correct one with sysctl. I tried to raise the issue
several times but never got a response.
