Which power-management package on an embedded ppc under etch?

[Guennadi Liakhovetski <g.liakhovetski@gmx.de>]

Hi all

I grepped apt-cache search and found the following packets for 
power-management on ppc:

laptop-mode-tools
pmud
pmud-utils
powermgmt-base
powersaved

reading apt-cache show didn't deliver a definitive reply either. Which 
package(s) is the most appropriate to just spin down an IDE disk after a 
period of inactivity, maybe try to clock down CPU (if it is ever 
supported), maybe run some user-provided scripts to, for example, spin 
down the fan in a non-standard way...

Thanks
Guennadi
