The driver didnt attach, otherwise you'd have seen a few more 'bktr' lines in 
your dmesg.

btsetup is a tool from kbtv1, the sort-of equivalent for kbtv2 is kbtv2-setup. 
It has an even more braindead UI, just sets up any supported device found 
(well, I hope so..). btsetup had an option to set sysctls for bktr, this 
functionality has been dropped from kbtv2-setup (so do it manually if needed)

PS to Fritz: for your problem with bktr tuning try sysctl with another tuner 
type (see bktr(4). The introduction of the microtune code into bktr a few 
years ago seems to have made some of the old hauppauge wintv cards 
problematic. Also, some cards (eg leadtek and maybe also some hauppauge wintv 
cards from that era) may have an unsupported tuner.
