Steve,

it may be true that the software stack can't handle volume being done in hardware, but the software stack can, and has, correctly handled the LCD brightness for ages correctly.

For the panel there is an hal property (correctly set on my x31 for example):

  laptop_panel.brightness_in_hardware = true

This is used by gnome-power-manager to let it know that the hardware notifications are just notifications and not action requests.
