To clarify, before someone jumps all over me: look inside
the PCI code, you'll see that PCI as a whole is registered
using the pm_*() stuff for power management. Yes, when
those callbacks get made, they morph into driver model calls.

Which means that PCI devices (like OHCI) don't fit into the
suspend/resume sequence in the way one would expect. It
might explain why I'm still seeing two equivalent suspend
notifications in the OHCI code...
