/mnt/cdrom is a directory, not a symlink.   Which I assume means the
installation hasn't worked?

Nope. It was a typo on my part. It is /dev/cdrom that should be a symlink (probably to /dev/scd0)

Tried that before -  "unknown device"   still

Your other message said that /dev/scd0 is a file that is 11 bytes long. It shouldn't be; it should be a pseudo-file entry -- in this case, a block device -- that provides an interface to the hardware. If you do "ls -l /dev/scd0", the result should be approximately this (this one is from my workstation):

brw-rw---- 1 root cdrom 11, 0 Jun 13 2001 /dev/scd0

The "11" here is not a size; it is a device-major number. Make sure your corresponding entry has the initial "b" (the indicator of a block device) as well as the 11, 0.

lsmod showed  sg  and scsi-mod.
After  'insmod ide-scsi'   ide-scsi appeared in the list too.
But trying 'insmod sr_mod'   just gives four error messages of
'unresolved symbol unregister_cdrom_R94f2f104'   and similar.

The absence of this module is probably the source of your problem, as it is the device driver for scsi CD-ROMs. modules.dep ssys it depends only on scsi_mod. I don't have enough info about your setup (kernel details, mostly) to know why you are getting ghe "unresolved symbol" errors, but the usual reasons are kernel-version mismatch or missing dependency. See what effect "modprobe sr_mod" has.

X-cd-roast seems to work quite happily without it, though.

That's because it accesses the device by (pseudo-)LUN, not through the block device /dev/scd0.
