           This driver provides support for the IBM Hard Drive Active Protection
           System (hdaps), which provides an accelerometer and other misc. data.
-          Supported laptops include the IBM ThinkPad T41, T42, T43, and R51.
-          The accelerometer data is readable via sysfs.
+          ThinkPads starting with the R50, T41, and X40 are supported.  The
+          accelerometer data is readable via sysfs.
 
-          This driver also provides an input class device, allowing the
-          laptop to act as a pinball machine-esque mouse.  This is off by
-          default but enabled via sysfs or the module parameter "mousedev".
+          This driver also provides an absolute input class device, allowing

           the awesome power of hdaps.
