But if they are not topologically ordered, then A wouldn't necessarily be 
before B on the list in the first place.

Of course, if we've mucked with the list by hand and made sure the 
ordering is ok, then that's a different issue. But your whole point seemed 
to be that the device could impose its own ordering in its suspend 
callback, which is not true on its own without external ordering.
