-	  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
-	  the awesome power of hdaps.
