ACPI methods belong to SATA/PATA targets, not PCI devices. The notification you get is something of the form \SB.PCI.IDE0.SEC.MASTER on sensible devices, and \SB.C043.C438.C222.C223 on anything from HP[1]. Somehow, you have to get from there to a specific SCSI host and target. By far the easiest way of doing that is to register them at device add time, which needs a small amount of cooperation from the SCSI or libata layers. And to register the notifications in the first place, you need to know the ACPI handles.
