[SCSI command timeout in sbp2 after resume; no nodemgr updates after resume]

AFAICT the reason is that the host adapter drivers (1394 low-level
drivers) ohci1394 and pcilynx lack proper .suspend and .resume hooks.
Such functionality seems only be present for Powermacs with Uninorth
chipset.

OHCI 1.1 table A-11 says (surprise!) that host adapters loose PCI
configuration and 1394 configuration when going into D3 state. We don't
backup and restore it yet. I could perhaps look into it in late spring
or summer.
