Sounds like your max6634 driver doesn't have i2c_detect() implemented properly. The lm75 driver does it "right" and all those false positive hits are weeded out by additional checks in the lm75 i2c_detect() implementation. It would be interesting to see a fully-functional driver using the bit-banging approach, but that requires somebody that cares about it. -Matt
