Tested latest v4.9 kernel, as suggested by Joseph Salisbury. The bug remains exactly the same: Backlight control does not work and there are no entries in /sys/class/backlight
Apart from that, this kernel makes the PC run slow (at least, a big latency is observed on the screen when typing on moving the mouse). This might not be related to the backlight bug , but I will uninstal the upstream kernel if no more testing is needed with it.
