It's a bit unfortunate that this is called "policy" as Chrome has a notion of
"policy" and it means something different.

Could you disambiguate in the comment a bit by using e.g. "power manager policy"
or "powerd policy"?

Not sure what you mean here -- this is already called
"UpdatePowerManagementPolicy()".  Do you mean you want it to be
"UpdatePowerManagerPolicy()" instead?

Yes, I was thinking of PowerManagerPolicy. That way, it should be a tad clearer
that this is not "policy" in the Chrome sense but policy in the sense of some
other entity, the power manager.

See my comment in the preferences.cc file - this can be expressed as a simple
bool.
