I have been trying to figure out how to use i2c on RaspberryPi, and the What is the difference between i2c-dev and i2c-bcm2708 mentioned here? I would assume the i2c-bcm2708 module is specific to the RaspberryPi's ARM processor, so then why should I also install the i2c-dev module?

i2c-bcm2708 is the low level driver. i2c-dev creates the convenient /dev/ entries
