I'm doing this part separately, please drop it - it has nothing to do with
the rest of the patch.
I'd also suggest that you just add a helper function like
int pm_event_powerdown(struct pm_message mesg)
{
return mesg.event >= PM_EVENT_SUSPEND;
}
or something, so that you can have code like
if (pm_event_powerdown(mesg))
pci_set_power_state(pdev, PCI_D3hot);
instead of the test for EVENT_SUSPEND/HIBERNATE explicitly.
Of course, the places that already do a switch-statement are much better
kept that way and just add PM_EVENT_HIBERNATE to the list.

Didn't you miss the apci_pci_choose_state() thing that also needs this
extension?

Looks like a missing close-brace to me there - you removed the final '}'.
Or am I blind?
Apart from those issues it looks fine to me.
