No trace of uevent_helper in udev code.
http://git.kernel.org/?p=linux%2Fhotplug%2Fudev.git&a=search&h=HEAD&st=grep&s=uevent_helper

No trace of uevent_helper or hotplug in /lib/udev/rules.d/

The hotplug helper /sbin/hotplug is now officially deprecated. The
control file /proc/sys/kernel/hotplug has moved to
/sys/kernel/uevent_helper, but it is expected to be disabled on most
systems in favor of udev and the netlink interface.

So this is an old legagy. We should drop it.
