Yes, the list of things to do is called the token table. I am working on getting permission to release it. As it is, I am releasing tokens as people ask for them, on a case by case basis.
I, personally, do not build or design our laptops, nor do I have any sway with those that do. Crying about it isn't going to help, sorry.
If you would care to move the discussion to libsmbios-devel, I would be more than happy to help you get the token you need and write a util/lib/whatever to do what you need. -- Michael

Oh, heavens. Could you people (and here I include pretty much everyone who manufactures laptops) please (please!) just implement the ACPI video extension? We're going to end up having to ship a 200K library for each and every laptop manufacturer who's decided to implement basic functionality in a proprietary manner, and it's going to make me cry.
(Which SMI do I need for brightness control? The libsmbios docs seem to be remarkably quiet on what functionality is actually available, and I'm not keen on calling things randomly :))
