It would be good, cause on my laptop LCD's highligting lamp is
automatically adjust after AC or battery is used.
On this laptop i had not manual control over it (i had on old Toshiba
Tecra 550) and that hurts. Default AC brigtness is far too high :-(
As well, while on AC i'd prefer to see fancy screensaver, on battery i'd
prefer to have waste no CPU/GPU power (no screensaver app) and turn LCD off.
I don't know of CRT's brightness has big impact on power consumption.
Of course gamma, color maps and similar funcitons belongs to X, but
hardware, like a lamp behind LCD might be as well controlled by kernel.
