Michael, sensors are really ST acceleromenters, but on Dell laptops, it is not possible to use them for other purposes. It is because ACPI export only one IRQ which detect hdd freefall. Accelerometer is 3 axes but there is no way (on MS Windows too!) to read status of axes. So for anything else as hdd freefall is driver useless.

It is separate ST Microelectronics accelerometer chip found in (probably) on motherboard. It can be found on laptop without GPS too.
