I believe it'll force the mapping.  Here's the relevant part of the
/etc/sysconfig/network-scripts/ifup script (reformatted to fit):

# remap, if the device is bound with a MAC address and not the right
# device num.
# bail out, if the MAC does not fit
if [ -n "${HWADDR}" ]; then     FOUNDMACADDR=`get_hwaddr ${REALDEVICE}`
    if [ "${FOUNDMACADDR}" != "${HWADDR}" ]; then
        curdev=`ip -o link | awk -F ':' -vIGNORECASE=1 '/$HWADDR/ { 
print $2 }'`        rename_device "${REALDEVICE}" "${HWADDR}" 
"${curdev}" || {
            echo $"Device ${DEVICE} has different MAC address than 
expected, ignoring."
            exit 1
        }
    fi
