Our runlevel S loads the usb stuff unconditionally like this:

#
# load usb drivers in runlevel S
#
case "${PREVLEVEL}${RUNLEVEL}" in
        N1|NS)
        test -f /etc/sysconfig/hotplug &&  . /etc/sysconfig/hotplug && test "$HOTPLUG_START_USB" = "yes" && {
        test -f /proc/cpuinfo || mount -n -t proc proc /proc 2>/dev/null
        test -d /proc/bus/usb || modprobe usbcore >/dev/null 2>&1
        mount usbdevfs >/dev/null 2>&1
        for i in $HOTPLUG_USB_HOSTCONTROLLER_LIST ;do echo -n $i" " ;modprobe $i >/dev/null 2>&1 ;done;echo
        sleep 3
        grep ^I: /proc/bus/usb/devices | grep HID && for i in input hid keybdev;do modprobe $i >/dev/null 2>&1 ;done
        }
        ;;
esac

This HOTPLUG_START_USB used to exist, but I'm not sure if we will leave
these HOTPLUG_START_{USB,IEEE1394,...} stuff for the next release. I
will probably remove it, have to think about it in the next days.

Well, maybe something like this could become part of a 'usb.rc boot' or
'usb.rc single' or something.

The only real issue is the /etc/sysconfig/ vs. /etc/default/
We should source both if they exist, it causes only one additional
stat() call.
The goal should be that the configuration is unified somehow, and not
spread all over /etc for the various distros.
