It doesn't seem to.
$ grep cdrom /etc/fstab
/dev/hdc /mnt/cdrom iso9660 noauto,user,ro 0 0
$ ls -l /dev/hdc
brw-rw---- 1 root cdrom 22, 0 Sep 21 2006 /dev/hdc
$ ls -l /bin/mount
-rws--x--x 1 root root 91492 Mar 15 2006 /bin/mount
uid=1000(pv) gid=100(users) groups=100(users)
And I do can mount /mnt/cdrom though I don't belong to cdrom group.
Nothing but perfection
