Well, everything laptop related is getting more and more and more complicated:
- disk spindown
- kernel laptop mode
- readahed
- battery monitoring
- suspend to disk
- suspend to ram
- suspend on low battery
- suspend on lid close
- powersaving for cpu
- powersaving for hd
- powersaving for wireless
- reconnect wireless after suspend

And we have a lot of different tools and different ways to control all this:
- laptop-mode-tools
- cpufreqd
- acpitool
- cpudyn
- pmscripts
- powersave
- gnome power monitor
- probably a KDE one too
- probably a lot more I haven't thought of yet

The problem is:
- most are poorly documented
- some rely on others, some require others, some conflict with others
- interdependecies are poorly documented

This leads to two problems:
- most of us can barely figure out how to get a laptop working with
good power management
- converts from other distros and newbies probably cannot at all

So, maybe someone can sit down, compare all the tools, decide on which
ones will be official (and installed by drakx on laptops), and make
sure no default tools require a backend that conflicts with the
official backend.  And then document it all.

I'd try to take this on, but I'm in the middle of the most insanely
difficult exams I've ever written.
