 i have the prototype first tablet, i tested the MXC6225 which was
installed on it: the only values given were 0x00 and 0xff.  the
MXC6225 is basically for ultra-low-cost devices where all you need to
know is:

    "is this device upright or is it on its side, yes or no".

a games console may wish to use an accelerometer (or tilt system)
where the motion of the device - a small tip to the left - is used in
essence as a mouse or analog joystick.

 i think there's a gnu/linux game where you have a ball-bearing that
you steer through obstacles by moving the mouse to "tilt" a surface.

 the MXC6225 would be completely and utterly inadequate for such a game.
