That patch wound up going into 3.7 as: From fba4e087361605d1eed63343bb08811f097c83ee Mon Sep 17 00:00:00 2001 From: Igor Murzov <e-mail> Date: Sat, 13 Oct 2012 04:41:25 +0400 Subject: [PATCH] ACPI video: Ignore errors after _DOD evaluation. There are systems where video module known to work fine regardless of broken _DOD and ignoring returned value here doesn't cause any issues later. This should fix brightness controls on some laptops.

Description of problem: The brightness control is not visible while pressing Fn-{F7,F8}. Version-Release number of selected component (if applicable): F17 fully updates to updates-testing, in particular kernel version: 3.6.3-1.fc17.i686.PAE How reproducible: 100% Steps to Reproduce: 1. Boot the machine. 2. Log to the KDE session. 3. Try to change the actual brightness using Fn-{F7,F8}. Actual results: Brightness doesn't work. Expected results: Brightness should be adjusted accordingly. Additional info: According to the[1] it could be a regression introduced in version 3.4-rc1. I've recompiled the 3.6.3-1.fc17.i686.PAE kernel with the following proof-of-concept patch[1] and it does fix the problem.
