Be careful with the above layout though. There is a lot of duplication (e.g. 
already with x86 there would be ../scripts/acpi vs.  ../scripts/apm vs.
../scripts/default). For instance, Xen might want to use some scripts from
../scripts/acpi and some from ../scripts/default.

But supposedly majority of the events are quite independent from the
machine and the power-type.

A long-term solution is to use more machine-independent APIs in the kernel;
perhaps more than anything else, both the above layout and the current
powerd(8) scripts are symptoms from not doing so.
