for all what I can see we have no analog demodulator on that card like
tda8290/95 or a 8290 integrated within a saa7131e chip. 
All other saa713x chips don't have an internal analog demod with an i2c
bridge to control the tuner.

That simply means there is no analog tuner and  the correct tuner type
for analog is tuner=4 TUNER_ABSENT. We can only configure the card for
auto detection as a saa7130 device, enable Composite and S-Video support
and maybe the remote if the IR controller is supported.

Rest must be found and done within saa7134-dvb.c like pointed.
Tuner is at 0x60/0xc0 and tda10048 at 0x08 (0x10 >> 1).
