	  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
	  <file:Documentation/hwmon/userspace-tools> for details.

	  This driver provides support for the IBM Hard Drive Active Protection
	  System (hdaps), which provides an accelerometer and other misc. data.
	  ThinkPads starting with the R50, T41, and X40 are supported.  The
	  accelerometer data is readable via sysfs.

	  This driver also provides an absolute input class device, allowing
	  the laptop to act as a pinball machine-esque joystick.

	  If your ThinkPad is not recognized by the driver, please update to latest
	  BIOS. This is especially the case for some R52 ThinkPads.

	  Say Y here if you have an applicable laptop and want to experience
