You want a line like the one below in your /etc/fstab:
/dev/mcd /cdrom iso9660 ro,user,noauto,unhide
I admit shamefacedly that I have lifted this straight from my Debian
system because it is to late at night.
You want to replace the "mcd" bit with whatever driver you are using. The
bit you are most interested in is after the "iso9660" bit. That is how to
allow user mounts read-only.
Best wishes,
Helen

It seems you don't need to. As root,
# chmod a+r /dev/acd0c (or whatever CD device you use)
# sysctl -w vfs.usermount=1
and if cd9660 is not in your kernel,
# kldload cd9660
after that, any normal user can just,
ben@strontium:~$ mount_cd9660 -r /dev/acd0c ~/cdrom
ben@strontium:~$ mount
/dev/wd0s1a on / (local, writes: sync 15 async 4472)
/dev/wd0s1e on /usr (local, writes: sync 33618 async 82663)
procfs on /proc (local)
magnesium:/usr/src on /usr/src (read-only)
/dev/acd0c on /home/ben/cdrom (local, nodev, nosuid, read-only, mounted by ben)
It may be a good idea to put the three root commands in
/etc/rc.local. This seems like a cleaner solution than using sudo. Doing
the same thing for floppies may be useful for some people, too (I'm sure
you can all work out how to do that).
