That appears to be what it means. You can type in su, hit enter, then type in the root password and mount it. I think you can edit the fstab file so that users can mount that too. I think you add "users" to the options. Example:
/dev/cdroms/cdrom0 /mnt/cdrom iso9660 noauto,ro,users 0 0
I think that works. Don't kill me if it don't though.
