So I just got the 3.16 kernel with the changes for all Windows 8 laptops.
And while I bought this laptop (Thinkpad x201s) in 2010, it seems a BIOS update added the “support” for Windows 8 (at least that's a guess from http://paste.debian.net/120230/ , I can provide full acpidump).
So this laptop where brightness keys where working perfectly using ACPI, has now the same issue, and I need to have something in userspace doing the job.

That's really a regression for me.
