I suppose this is just an RFC?
We don't want to lose to SCSI device suspend, so merging that would be a
regression AFAICS? While we're still married to the SCSI layer, we need
to do suspend through sd.c and similar paths.
I also wonder if any developers or users make use of the ability to
suspend/resume individual pieces of hardware, as is (somewhat) supported
in ata_piix in 2.6.17-rcX.
