Description of problem: Answer to question "How do I turn enforcing on/off at boot?" in FC5 SELINUX FAQ point to missing config file /etc/sysconfig/selinux. Please, chage it to /etc/selinux/config. (At least the answer to previous question in the FAQ, i.e. "How do I turn SELinux off at boot?" points to / etc/selinux/config)
