First step will be to verify that setting the brightness manually (either using xrandr or through /sys/class/backlight/*/brightness) is still functioning correctly. If that is, we can assert that the bug lies in the ACPI handling of the key presses. Otherwise, the bug lies somewhere in the chain of applying the brightness (which may lead us back to ACPI again...).
