Don't ask me; I totally suck at naming! Though I can, and do, blame
Havoc for the name HAL :-). With this disclaimer in mind I'd still go
for GetPreferPowerSavings() but at the same time I'm not attached to the
API name.

I'd just add it right away and wait for people to file bugs because of
the fact that certain apps don't use it. But that's just me ;-)

Yup, it is an implementation detail private to g-p-m, kpowersave and so
forth. I thought I would bring it up anyway, since it helps illuminate
why such a method is useful.
