... and I managed to get this working without a patch. You just
need the following as your bbappend:

----------------
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"

SRCREV_machine = "${SRCREV}"
----------------

The key is the addition of SRCREV_machine. It deals with the issue
that I mentioned with the kernel recipes. They have a series of patches
that are already on the branch being built. But yet the SRCREV backs
the branch off and allows the patches to apply (something I wouldn't
do .. but that's not the point).

The linux-yocto validation can do a similar back off, but it currently
triggers on SRCREV_machine, which wasn't set .. this is already fixed
in my current series that will go out for Yocto 1.7.

After this:

]> pwd
/home/bruce/poky/build/tmp/work/cubox_i-poky-linux-gnueabi/linux-cubox-i/3.0.35-r0
yow-bashfiel-d3 [/home/bruc.../3.0.35-r0]> grep CONFIG_VIDEO_ADV7180 
linux-cubox_i-standard-build/.config
CONFIG_VIDEO_ADV7180=y

Note, the fragment you were working with needs this:

 > cat videoin.cfg
CONFIG_VIDEO_CAPTURE_DRIVERS=y
CONFIG_VIDEO_ADV7180=y

Or you'll be missing a dependency and have the config dropped from
the final .config.
