The easiest way is to edit tuner-core.c, search for 'tuner_status' and
then change the line:
tuner_info("Tuner mode: %s\n", p);
to something like
tuner_info("My Tuner mode: %s\n", p);
Compile, install, rmmod ivtv tuner, modprobe ivtv, and then run
ivtvctl --log-status. If the new text appears then you've got the right
tuner module. Otherwise there is probably a duplicate tuner module
around.
