Can't we adapt same code from SAA7134_BOARD_PHILIPS_EUROPA ?
Here the comment present in subroutine saa7134_board_init2 in 

The Philips EUROPA based hybrid boards have the tuner connected through 
the channel decoder.
We have to make it transparent to find it.

Perhaps AverMedia did similar arrangement with different gpio addresses 
or "tricks" ?

I lack completely the "big pictures" and my knowledge of the sources is 
very near to zero, then if you can point out where put the hands, I can 
try to do something.
Otherwise, if there is to write from scratch many lines of code, I am 
not a C progammer and I am unable to do it.

For now I tried to add following lines (copied from Europa card) in 
saa7134_board_init2 without obtaining any different results:

        struct tuner_setup tun_setup;

        u8 data[] = { 0x07, 0x02};
        struct i2c_msg msg = {.addr=0x08, .flags=0, .buf=data, .len = 
        i2c_transfer(&dev->i2c_adap, &msg, 1);

        tun_setup.mode_mask = T_RADIO | T_ANALOG_TV | T_DIGITAL_TV;
        tun_setup.type = dev->tuner_type;
        //tun_setup.addr = dev->tuner_addr;
        tun_setup.addr = ADDR_UNSET;

        saa7134_i2c_call_clients (dev, TUNER_SET_TYPE_ADDR, &tun_setup);


Another thing, I received this email from Martin Ottmár that is'nt in 
linux-dvb Archives <http://www.linuxtv.org/pipermail/linux-dvb/>.:

I espected the module tda9887 were loaded by saa7134, but is'nt so.
