Kernel module works if there's an SMO8800 or SMO8810 in
/sys/bus/acpi/devices/. The dell-smo8800 is already merged in kernel
3.16, so you'll need an utopic kernel to use it at least for now.

If there's any issue with this package, please let me know, thanks.

Title:
  Dell laptops' ST Microelectronics Free Fall Sensor (accelerometer)
  [pnp:8810] cannot be detected at all

Status in linux package in Ubuntu:
  Confirmed

Bug description:
  CID: 201201-10339 Dell Latitude E6530 [1]
  CID: 201307-13941 Dell Latitude E5440 [2]

  According to the information provided by Dell, these systems should have an accelerometer on the motherboard (Free-Fall sensor), but it cannot be detected at all
  (cannot be found in  /proc/bus/input/devices)

  If using windows, it shows ACPI/SMO8810 in device manager
  If you run "lspnp", you can see: 
  00:0c SMO8810 (unknown)
