As Alan mentions in another thread, what is needed is true hotplug support,
which is difficult with some controllers for which we have poor (or no)
documentation. I wouldn't hold your breath.
As for pass-thru standby/sleep commands, as long as the pass-thru patch got
into mainline, try a very recent version of hdparm which should understand
sending the ATA commands over SCSI (libata).
