Well, you hit the snag that's hittable. First suggestion would be try to 
use type 29 for both. I seem to recall they were compatible from the IVTV 
lists.

However, if not, you may need to mess around in the driver source. This is 
how I do it:

Look for the part in ivtv-driver.c that says:

        if( tuner > -1 ) {
                ivtv_call_i2c_client(itv,
                                     IVTV_TUNER_I2C_ADDR,
                                     TUNER_SET_TYPE,
                                     &tuner );
        }


Replace with:


     if (itv->card_type != IVTV_350_V1) {
                          IVTV_DEBUG(IVTV_DEBUG_INFO, "Attempting LG 
Tuner type 28\n");
                          tuner=28;
                          ivtv_call_i2c_client(itv,
                                     IVTV_TUNER_I2C_ADDR,
                                     TUNER_SET_TYPE,
                                     &tuner );

        }
       if (itv->card_type == IVTV_350_V1) {
                          IVTV_DEBUG(IVTV_DEBUG_INFO, "Attempting 
type 29\n");

                          tuner=29;
                          ivtv_call_i2c_client(itv,
                                     IVTV_TUNER_I2C_ADDR,
                                     TUNER_SET_TYPE,
                                     &tuner );
        }


This code just checks the version of the card you're loading the driver 
for and calls the corret tuner for that card.

Set the tuner variables to whatever is appropriate for your card and skip 
speccing the tuner in modules.conf.
