Hardly so.  We need to be able to query state and command the bay from
userspace.  We need to support non-libata devices.  We don't need, but want,
notifications that can be easily flagged by userspace as being related to
bay/dock ejections and insertions (for OSD).

What makes bay obsolete is the rework on the dock driver that adds all bay
functionality to dock.c... and that ain't even on 2.6.27, AFAIK.
