This looks unuseable at the moment.

Interesting. :)
Especially as I just can quote you to get it working again.

There seems to be something messed up with the eeprom detection.
First unload all related modules and make sure only the ones from the snapshot
are present at all. Then "depmod -a" and "modprobe -v" to see you load only from 
/lib/modules/uname -r/v4l2.

Do you have a radio connector or not? The TCLs with radio can have Philips API.

Assuming the TCL 2002MI 3, eeprom #84 works as tuner=37, what seems probable, but you 
can't find a way to circumvent the auto misdetection, several trails should be viable 
for testing, but as the eeprom stuff doesn't look very promising maybe simplest is to
create a new card entry first for tuner testing and fix that later.

Maybe this can work for it.
