No, it didn't.  I could make all PCI async, provided that the ACPI subtree was
resumed before any PCI devices.  [Theoretically I can make that happen by
moving ACPI resume to the _noirq phase (just for testing of course).  So I can
try to make PCI async in addition to serio and USB, plus i8042 perhaps, which
should be sfficient for the nx6325 I think.]

Making all async always hanged the boxes on resume.
