... and which has the ability to break platforms if the PM domain is
not already available.

What's wrong with the patch in the link above _combined_ with a patch
which addresses the concern I have with that patch: build a list of
the failed-to-register devices, and retry them later - maybe from a
late_initcall(), or a similar mechanism?

My view is the risk to existing systems is _too_ high to apply either
this patch, or the patch you link to above, and I refuse to play the
"lets apply it and see if we break anything" lottery with this.
