I have it successfully running with the `od' driver.  (You can find it
in the /xperimnt section of 2.1, in any 2.2-current system, and now
even in 2.1-stable [since today].)  It's a:

(ncr0:3:0): "SONY SMO-C501-09   KG 2.13" type 0 removable SCSI 1
od0(ncr0:3:0): Optical 281MB (576999 512 byte sectors)

The drive is actually an ESDI drive with an ESDI-to-SCSI bridge
dedicated for MO drives.  The biggest problem is that it always
insists on being ``type 0'' (direct access), as opposed to ``type 4''
(optical).  2.2-current contains a kludge to override the driver
assignment that is normally based on the device type.
