First of all, thanks for catching the deprecated property and changes in
the input.h.

As for testing, both can be triggered with magnets. The lid switch is
near the camera on the top of the display. For me, the tablet-mode
sensor is around 1/3 up from the bottom (assuming camera is the top) on
the back side of the device. Not sure how that would line up for you
though...
