Problem 20: No brightness adjustment on AC power

I thought I have discovered all the issues, but it looks like there is more to come :( The newer version of powersaved thinks that my hardware does not allow for screen brightness adjustment. Thus, when I am on AC power, my screen remains unnaturally bright. But it worked perfectly in 10.0, dimming my screen. The spictl utility says that /dev/sonypi does not exist, and refuses to adjust screen brightness, either. This may be related to the hotkey-setup being disabled - I will try to re-test this first.
