I also need the output of dmidecode and I do the following in by boxes:

/etc/rc.securelevel:

if [[ -x /usr/local/sbin/dmidecode ]]; then
/usr/local/sbin/dmidecode > /var/run/dmidecode.boot
fi

It runs the script at an early stage, before the change of kern.securelevel
so access to /dev/mem is allowed.
