On my ARM9 system, with a Buildroot made Rootfs (without udev), 
following script is working to load helper firmware (save it as 

if [ "$FIRMWARE" != "" ]; then
        echo 1 > /sys/$DEVPATH/loading
        cat $HOTPLUG_FW_DIR/$FIRMWARE > /sys/$DEVPATH/data
        echo 0 > /sys/$DEVPATH/loading

If it can help...
