Ok here on my laptop it's definitely hardware-based, the backlight doesn't work in the first moment, when the laptop is cold. I just booted my cold laptop into 3.0.7 linux-rt and it happened there as well.
It seems that we have symptomatically similar but unrelated problems, then. I've only ever seen this problem with 3.1, and never with any earlier kernel.
