I'm looking through the dm1105 code that I have in 2.6.33-rc4.  I have a
block that reads:
                dm1105dvb->fe = dvb_attach(
                        si21xx_attach, &serit_config,
                        &dm1105dvb->i2c_adap);
                if (dm1105dvb->fe)
                        dm1105dvb->fe->ops.set_voltage =
                                                dm1105dvb_set_voltage;

I have looked through the code for si21xx.c, and I see that you wrote that
as well.  You have been very busy!!  

I did rmmod si21xx, then insmod si21xx debug=1.

I then rmmod dm1105, insmod dm1105.

dmesg reports:

Does this shed any light on the matter for you?

Thanks,

Paul
