In the lm90 case it's almost certainly because you have the firmware and 
Linux trying to access the chip at the same time. Since it has indexed 
registers, this fails very miserably. I'm surprised that the TV card 
driver has any effect - it should be on an entirely spearate i2c bus. 
Are you sure you don't have lm90 loaded in that case?
