The key is in the mount options in fstab.  It's what allows you
to do mount /media/floppy (which gets the rest of the info from
fstab, including the info that allows a normal user to do the mount).

The "users" option is a special option in this case.  Mount understands
the "users" option when it gets it from /etc/fstab.
