It appears some systems haven't a dock but a bay. In a thinkpad, you
could hotplug cdrom/battery/harddisk in the slot of cdrom, but it's not
a dock. libata should handle it well (but it doesn't handle _EJ0
currently, I have a patch in above bugzilla).

But you are right, acpi dock driver should be extended to support bay.
I'll give it a try.
