But why not provide a simple interface that allow non X 
tools/applications/daemons to change the brightness without reinventing again 
the wheel again and again. Nobody force X or X applications to use this 
interface, but they can. And I mean a simple interface as we have now in HAL, 
providing access to sysfs (and some old proc interfaces, we may don't need in 
the future) and some special tools as on Dell machines.
