As we know that our APS sensor is implanted in our Thinkpad. The similar sudden motion sensor is in Macs. But they different chips. I m just wondering if it is possible to load AppleSMS.kext. and maybe modify FakeSMC to collect smc data from APS (SMS).
-Apple uses the Kionix KXM52-1050 three-axis accelerometer chip, with dynamic range of +/- 2g and bandwidth up to 1.5 kHz.
-The measurements are physically performed by an Analog Devices ADXL320 accelerometer chip

We also know that our APS collects data from EC.

Continue digging. Maybe the linux kernel extension can help us a bit.
