That sounds quite reasonable. Does it need to do anything other than
park the head and suspend the command queue for that device?
(On an only slightly related note, for full ACPI support of PATA, we're
supposed to use the _GTF interface. This returns a set of taskfile
commands that are then supposed to be executed by the host. However, at
the point where we want to do this, the IDE queues haven't been
restarted. Is the best solution here just to add a trivial and stupid
IDE driver for managing the disks when we don't want userspace doing
anything with them?)
