I would say to look in /media for the mount point used for the cdrom, but you are using such an old distro, I don't know if SuSE adopted that convention ( from Linux Standard Base ) yet. The current SuSE distributions use udev to create devices, mountpoints and device links automatically. When that happens, it creates a temporary mount point under /media using the label of the disk as the name of the mount point.
You could setup sudo to allow you to run the mount command to mount a cdrom. ( Use visudo as root )
# Uncomment to allow people in group wheel to run all commands
# %wheel ALL=(ALL) ALL
# Same thing without a password
# %wheel ALL=(ALL) NOPASSWD: ALL
%users ALL=/bin/mount /media/cdrom,/bin/umount /media/cdrom
# %users localhost=/sbin/shutdown -h now
Then a user can run "sudo mount /media/cdrom" to mount the CD disc.
Look in the "man mount" and "man fstab" manual pages. You can use the option umask=0000 or uid=<youruserid> to allow everyone or just yourself access. For removable devices, be sure to use the noauto option.
Please read through the "man mount" man page. Some options may have changed, i.e. nls or utf8 options.
