nautilus-cd-burner, cdrdao, & device names ?

[Dr. Gary E. RAFE]

I'm in the process of setting up a FreeBSD-6.2/Gnome2 
notebook for a friend, and I'm having trouble
getting the built-in CD copy function of the Gnome desktop
to work properly.

As directed in the FreeBSD Gnome2 FAQ,
I found the cdrdao command line used by nautilus-cd-burner:

# nautilus-cd-burner --source-device=/dev/acd0 
launching command: cdrdao read-cd --read-raw --datafile /tmp/image.iso.TPHIOT --device /dev/acd0 -v 2 /tmp/image.iso.TPHIOT.toc 
cdrdao stderr: Cdrdao version 1.2.1 - (C) Andreas Mueller <andreas at daneb.de>
process stdout: EOF
cdrdao stderr:   SCSI interface library - (C) Joerg Schilling

Note that cdrdao wants its device in "bus,id,lun" form (e.g., 1,0,0).

When I issue this cdrdao at the command line:

# cdrdao read-cd --read-raw --datafile /tmp/image.iso.TPHIOT --device /dev/acd0 -v 2 /tmp/image.iso.TPHIOT.toc 
Cdrdao version 1.2.1 - (C) Andreas Mueller <andreas at daneb.de>
  SCSI interface library - (C) Joerg Schilling
  Paranoia DAE library - (C) Monty

Check http://cdrdao.sourceforge.net/drives.html#dt for current driver tables.

ERROR: Cannot open SCSI device '/dev/acd0': Open by 'devname' not supported on this OS
Supported SCSI transports for this platform:

Transport name:         CAM
Transport descr.:       Generic transport independent SCSI (Common Access Method)
Transp. layer ind.:
Target specifier:       bus,target,lun
Target example:         1,2,0
SCSI Bus scanning:      supported
Open via UNIX device:   not supported
ERROR: Please use option '--device [proto:]bus,id,lun', e.g. --device 0,6,0 or --device ATA:0,0,0
ERROR: Cannot setup device /dev/acd0.

Now, when I change "--device /dev/acd0" to "--device 1,0,0" at the
command line, cdrdao runs to completion
(albiet, not as fast as dd,
which doesn't seem to work with HAL enabled).

Short of mucking around with the code of nautilus-cd-burner
to introduce the proper SCSI device name for cdrdao
(something I'd rather not have to do),
where to from here to get this to work as it should ?
