it's even kinkier than that.  despite dmesg of

    cd0 at ahc0 bus 0 target 4 lun 0
    cd0: <TEAC CD-ROM CD-532S 1.0A> Removable CD-ROM SCSI-2 device 
    cd0: 20.000MB/s transfers (20.000MHz, offset 16)
    cd0: Attempt to query device size failed: NOT READY, Medium not present
    cd1 at ahc0 bus 0 target 5 lun 0
    cd1: <YAMAHA CRW4416S 1.0f> Removable CD-ROM SCSI-2 device 
    cd1: 8.333MB/s transfers (8.333MHz, offset 31)
    cd1: cd present [270542 x 2048 byte records]

i can put a mountable disk in the TEAC and it will mount only on cd1c (note
the 1 not 0), and vice versa with cd0c.  i.e. they are reversed in some way.

and let's remember that the kernel config says

    disk  cd0 at scbus0 target 4 unit 0
    disk  cd1 at scbus0 target 5 unit 0

and, if i put an audio cdrom in the teac and xmcd -dev /dev/rcd1c, it sees
the cd, gets the title etc. from the database, looks like it plays, but no
sound.

i will play more after a bit more sleep.
