I'm sorry to contradict you and I would also understand you if you didn't CRY.

Following is a part of the bug report to pmud from laptop-mode-tools author 
Bart Samwel:

"I've got a patch to pmud that makes it execute, in addition to
pwrctl-local, all files in the directory /etc/power/pwrctl.d. I need this
because I'm working on laptop-mode-tools, and I can't find a failsafe way
to hook into events provided by pmud like I can with apmd and acpid."

This means that the laptop-mode-tools won't connect to any power management 
daemon running on powerpc. Due to this laptop-mode-tools won't run 
out-of-the-box on powerpc machines, right? You need to add the command to the 
control script by hand. Otherwise laptop mode wouldn't be changed if power 
source changed. That the laptop-mode-script must also be lauched at boot time 
is only a workaround for insufficient quality of the PM-daemons.

IMHO laptop-mode is a dynamic option that must adapt to changing conditions. 
This can only be done in conjunction with a power management daemon. Anything 
else doesn't make much sense.
