I do get 4096.
Just had another good look at my notes, I also changed the init-file (Added 
the ulimit-statement here):
***
start() {
        checkconfig || return 1

        [ -f /var/log/apache2/ssl_scache ] && rm /var/log/apache2/ssl_scache

        ebegin "Starting ${SVCNAME}"
++++        ulimit -n 4096
        ${APACHE2} ${APACHE2_OPTS} -k start

        i=0
        while [ ! -e "${PIDFILE}" ] && [ $i -lt ${TIMEOUT} ]; do
                sleep 1 && i=$(expr $i + 1)
        done

        test -e "${PIDFILE}"
        eend $?
}

***

I don't think there is a consistent method of making this change more 
permanent.
