One of these motion sensors was also popular on some HP laptops, and,
IIRC, it can also attach through ACPI.
I wrote an OpenBSD driver a while back, and it was fully tested:
I also wrote an hptd(4) for OpenBSD and FreeBSD, which is the ACPI
attachment of said lisa(4) driver, but, IIRC, it might not have been
fully tested due to a lack of hardware, and was never committed
anywhere. Search in OpenBSD and FreeBSD archives for the details.
