Please add drm.debug=0xe and drop loglevel=0.

Is this what you keep getting in dmesg when you hit the hotkeys?

[   52.186865] ideapad_laptop: Unknown event: 15

Are you supposed to be using ideapad-laptop.c? For some reason it doesn't
recognize your the events being generated.

What do you have under /sys/class/backlight? Do the backlight interfaces work
by echoing values to the brightness files?
