I'm glad that I looked again, I though there was an error without my
clean up series .. but what I was seeing was a legitimate double
application of the patch.

What error where you seeing when you tried a bbappend like so:

------------
FILESEXTRAPATHS_prepend := "${THISDIR}/${PN}-${PV}:"

inherit kernel
require recipes-kernel/linux/linux-yocto.inc

COMPATIBLE_MACHINE_cubox-i = "(cubox-i)"

SRC_URI += "file://videoin.cfg"
--------------

Your error message will set me straight .. and tell me if it is just
the late night hacking fooling my eyes .. or not!
