Well, not straight off, no. I changed my driver a bit more to load my 
specific tuners to get that working. Here's the relevant section of code, 
which should work if you have a 350 card with the microtune and a 250 
card with a type 29 tuner. If you two 350 cards you'd have to find a 
slightly different way to determine which card should load what tuner:

(note, tuner type should not be set in modules.conf if you do it this 
way.)


        if (itv->card_type != IVTV_350_V1) {
                          IVTV_DEBUG(IVTV_DEBUG_INFO, "Attempting LG 
Tuner\n");
                          tuner=29;
                          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 
TDA9887 and Microtune 4049\n");

                          tuner=44;
                          ivtv_call_i2c_client(itv,
                                     IVTV_TUNER_I2C_ADDR,
                                     TUNER_SET_TYPE,
                                     &tuner );


                          ivtv_call_i2c_client(itv,
                                       IVTV_TDA9887_I2C_ADDR,
                                       AUDC_CONFIG_PINNACLE,
                                       &tda9887 );
        }

(yes, its' a horrendous way of doing it, but as far as I could tell off 
the mailing list they're working on getting tuner autoprobing into the 
driver in the next version which should solve the problem in a better 
way).
