	  sensors and various additional features such as the ability to
	  control the speed of the fans.  If you want this support you
	  should say Y here and also to the specific driver(s) for your
	  sensors chip(s) below.

	  To find out which specific driver(s) you need, use the
	  sensors-detect script from the lm_sensors package.  Read
