Yes you hit it ;). I'm read directly from the ACPI Embedded Controller.
If available I use ACPI ec_read function if not I use my own one. See

It'd be good to create hooks in the kernel for getting infos about
hardware, and every module can use them if wants. See
in console and apm/omnibook code for examlpe.
