-This driver provides support for the accelerometer found in various HP
-laptops sporting the feature officially called "HP Mobile Data
-Protection System 3D" or "HP 3D DriveGuard". It detects automatically
-laptops with this sensor. Known models (for now the HP 2133, nc6420,

-automatically oriented on standard way (eg: you can directly play

 Another feature of the driver is misc device called "freefall" that
 acts similar to /dev/rtc and reacts on free-fall interrupts received
 from the device. It supports blocking operations, poll/select and
 fasync operation modes. You must read 1 bytes from the device.  The
 result is number of free-fall interrupts since the last successful
-read (or 255 if number of interrupts would not fit).
