I was mistaken in thinking that my patch fixed this. It only works for
1 drive, as does at acd^H^Htapi-cd.c rev.1.148.
Some boot messages:

These drives now have the following behaviour for eject/close:
cd0, acd1, cd1: eject and close just work
acd0: eject works. Close fails with EBUSY. None of
acd_start_stop(cdp, [0-3]) (called from ddb, ignoring errors) closes
the tray when it is open.
The related bugs in the cd driver are only that the messages are too verbose.
The above boot messages show only some of them. Eject + close gives the
following messages (all unwanted):

This is with my modified version of scsi_cd.c. The current one is similarly
verbose, but doesn't do as many read-capacity's.
