Hi Andy, Marc and all list members! Thanks for your answers!

Yes Andy, I know! I'm trying with saa7134 and have tested all cards
listed in kernel source's CARDLIST.saa7134 and all these reported "Huh,
no eeprom present". After that I've tested with all tuners listed in
CARDLIST.tuner with the same card=56 parameter and the results were
similar: the same "no eeprom" message and a blue screen in TV input
mode.

With this two options, I have these interesting messages in kernel log:

Card is found at 0x96, but what tuner and card number combination may
work for this card? What other debugging information can I supply to add
this card to the list of supported cards in saa7134 module?

Thanks! Regards.
