It looks like none of the fields in the acpi_ibm module work on the X230.

Maybe we're somehow mislocating the EC?

And yes, the direct calls via acpi_conf work.

So how's the button press stuff supposed to work? eg, if hit fn-F8/F9
to decrease/increase brightness. Is this supposed to be totally
handled by the ACPI code? Or is it handled by acpi_ibm_eventhandler()
somehow?
