1) I would like to be able to change the brightness also if I'm on my laptop 
on console and remove the AC plug (e.g. in a system wide policy daemon that 
handle basic powermanagement if no desktop application handle it).

2) It's part of powermanagement (at least on laptops) and we should have a 
common interface for that. I don't like to call 3 or more different 
interfaces to do simple powermanagement tasks (like get battery/AC info from 
one, get/set brightness from another and call SetPowersave on an other 
again ...). 

3) Provide X a DBus interface for this? If not: is this planed? You maybe 
don't want to depend on X libraries. A DBus interface is more usefull and 
independent (you don't need to link against a X lib, ...).
