You don't.

However, you have two completely different tuners (Philips PAL_BG 
(FI1216 and compatibles) and Temic PAL_BG (4006FH5)), so if they're both 
acting the same way, it's most likely the input signal or your 
modprobe.conf settings.

Make sure the only two lines in modprobe.conf are:

# ivtv modules setup
alias char-major-81 videodev
alias char-major-81-0 ivtv

The right tuner types...

You currently have a debug option specified for ivtv.  It's preventing 
tveeprom output from showing during normal module loading.  Therefore, 
fix your modprobe.conf as above, and you should see the tveeprom info in 
/var/log/messages.  I don't know why you're not finding the information 
on a manual load of tveeprom, but I would guess that the tveeprom module 
is failing to load (i.e. maybe you didn't have ivtv loaded at the time...).

Easiest fix is to fix your modprobe.conf.  See Jarod Wilson's HOWTO 
(specifically, the part on capture card configuration) for more info.  
Even if you're not using Fedora Core 2, the info still applies.
