This can be done in userspace with the i2cdetect tool (part of the lm_sensors package) instead. What's more, i2cdetect gives more control on the way the bus is scanned, and is safer (i2c-keywest currently scans reserved addresses and doesn't properly handle the famous 24RF08 corruption case.) Thus, I would propose that this module parameter be simply dropped.
