One thing that did occur to me, I don't know how useful it would be,
but the eventhandler code does have priorities that are used to sort
the list entries when they are inserted.  You _could_ assign differing
priorities to the leaf devices so that the powerhooks for these
devices get run before the bus devices which would be at a lower
priority.  I am not saying that is what must be done but the
eventhandler code does cater for ordering the list elements beyond the
order in which the hooks were registered.

I will have a look into it...
