i agree.  i'd welcome a powerd patch for this -- i think it would
take the form of a helper executable that listened for dbus
control messages, and informed powerd via its usual event mechanism.

in the short term the timer that powerd currently uses could be
adjusted, but clearly that's not a real solution.

(i haven't looked at them in a while.)
