Not a bad idea, though I'm really not sure that it shouldn't just be
removed entirely.  It is a bad idea to not stop the disk on
suspend/shutdown since it leaves the disk to take an emergency head
retract, which isn't good for it.  At the very least it should park
the heads, though currently libata does not handle the scsi cmd for that.
