Bug description:
  Problem: 
  Kernel detects presence of accelerometer hardware yet the accelerometer is not functional.

  Device:
  I: Bus=0019 Vendor=0000 Product=0000 Version=0000
  N: Name="Acer BMA150 accelerometer"
  P: Phys=wmi/input1
  S: Sysfs=/devices/virtual/input/input3
  U: Uniq=
  H: Handlers=event3 js0 
  B: PROP=0
  B: EV=9
  B: ABS=7

  
  Looking in /devices/virtual/input/input3 there should be a position file that relays axis data via x, y, z tilt counters.

  For lenovo, it seems the hdaps driver is not longer available, nor is
  there an opensource equivelant available.
