FYI, I just automatically updated to the newer kernel (*.0-69-generic), however, shortly before the upgrade I noticed that it wasn't working with the previous one as well.

You are running daily on a Freya install. Due to changes to UPower this settings key probably did not exist back in the version that's in Freya.
So we should probably not pay any attention to this bug report right now, as we do kind of have the policy to not force ourselves to be compatible with old code.
