Since the newer hardware lacks an ACPI brightness controller and it is possible to have userspace deal with the brightness in these cases, it seems to me that the solution to the issue lies outside of the fujitsu-laptop module (which is focussed on the custom devices in the laptops). I am more than willing to be convinced otherwise, but at present this seems to be the prevailing line of thought.
