I can confirm that the module is not at fault, /sys/class/backlight /acer-wmi/brightness reports 0 when the screen is at minimum brightness, and 15 when at maximum brightness, and further key-presses produce no effect on the actual screen brightness nor the reported value. However, the gnome brightness meter still moves up and down past those limits, as if it is keeping track of a running total, rather than reading the current value from any authoritative source.
