As you mentioned, we most probably need a special config entry
for your card. As far as i know, it has no firmware eeprom for
the channel decoder.
To test this, you can try the following:
In saa7134-dvb.c, line 873, struct tda1004x_config philips_tiger_config
change the entry
	.request_firmware = NULL,
to
	.request_firmware = philips_tu1216_request_firmware,

The locaion of the firmware image depends on the distribution and
version you use. Its name is dvb-fe-tda10046.fw
