I2C mainboard interfaces
CONFIG_I2C_MAINBOARD
  Many modern mainboards have some kind of I2C interface integrated. This
  is often in the form of a SMBus, or System Management Bus, which is
  basically the same as I2C but which uses only a subset of the I2C
  protocol.

  You will also want the latest user-space utilities: you can find them
  in the lm_sensors package, which you can download at
  http://www.lm-sensors.org/
