Maybe one thing which could make things more clear to others would be to 
explain which things, potentially related to power management, are managed by 
what (or not) and how much they actually affect power consumption, like:

* managed via FooApplet or a hardware switch
* saves a lot of energy when disabled

This could contain:
-Wired Network
-Sound hardware
-Builtin camera
-other builtin peripherals ?
-Screen Brightness
-CPU frequency
-(Rotating) Hard Disks
-strigi/nepomuk indexing

(I know a lot of these things have been touched in the thread, but having this 
information in one place would be a good thing. Also e.g. you stated that CPU 
settings were removed due to request from the kernel developers, but now 
people not involved (like me) wonder how this is managed now by the kernel 
(e.g. for writing emails I'd be fine with one of my two cores being powered
