Try enabling the commented line again (~ line 290):
        buf[3] = 0x50;  // old
//      buf[3] = 0xf4;  // pinnacle

Try adding this:

        buf[0] = AGC_TARGET;
        buf[1] = 0x20;
        mt352_write(fe, buf, 2);

before this (~ line 320):

        if (state->config->no_tuner) {
                /* start decoding */
                mt352_write(fe, fsm_go, 2);

Also this should give proper signal strength readback (~ line 420):

        u16 signal = (mt352_read_register (state, AGC_GAIN_3) << 2) |
                    ((mt352_read_register (state, AGC_GAIN_2) >> 6) & 3);

At least some ideas of stuff you could try :)
