Hello everyone.
After installing official 10.10 I have stumbled upon a bug that makes me unable to control brightness with fn hotkeys. These were working perfectly under Mavericks.
Basically pressing the FN+F4/F5 key combination once makes OS X think that the keys are still held down, thus it'll be trying to increase/decrease the brightness until I press the opposite key. After that, it just won't react for the FN+F4/F5 keypresses.
Here's a video of me reproducing the issue:

Notice that the OSD won't go away, which (I guess) indicates that the OS still thinks that the keys are held down.
I have tried installing RehabMan's ACPIBacklight.kext, but this completely disabled brightness control.
I have tried to fix this with reverting the AppleBacklight kext, it didn't help.
I have applied the DSDT patch for renaming the GPU and the other HD3000 brightness patches.
I was running the exact same DSDT+SSDT on Mavericks with no such issues.
Thank you for your time.
EDIT:I completely forgot about attaching IOREG. Here it is.
