[meta-freescale] Linux kernel version

I'm trying to get a Yocto based image built for a modified sabre board.

I received some kernel patches against uboot 2009.08 and imx-linux-3.0.35-4.0.0.

When I build a default project (eg. fsl-image-dfb) for machine imx6dlsabresd (I didn't manage to add an own machine configuration, but will dig developer manual before asking regarding that ...), always linux-imx-3.10.17-ga_1.0.0 is built. Setting

PREFERRED_VERSION_linux-imx_mx6 = "3.0.35"

causes in build-errors of imx-lib_mx6:

| arm-poky-linux-gnueabi-gcc  -march=armv7-a -mthumb-interwork -mfloat-abi=hard -mfpu=neon -mtune=cortex-a9 --sysroot=/home/sno/fsl-release-bsp/first-test/tmp/sysroots/mediapilot -DIMX6Q -I/home/sno/fsl-release-bsp/first-test/tmp/sysroots/mediapilot/usr/src/kernel/include/uapi -I/home/sno/fsl-release-bsp/first-test/tmp/sysroots/mediapilot/usr/src/kernel/include                  -I/home/sno/fsl-release-bsp/first-test/tmp/sysroots/mediapilot/usr/src/kernel/drivers/mxc/security/rng/include                  -I/home/sno/fsl-release-bsp/first-test/tmp/sysroots/mediapilot/usr/src/kernel/drivers/mxc/security/sahara2/include -Wall -O2 -fPIC -c pxp_lib.c -o pxp_lib.o

Well - I've seen xbmc project from Stephan (https://github.com/wolfgar) provides a libcec which seems to have similar content. I'm a bit torn how to move out of that...

Is it reasonable to port the received kernel patches to linux-imx_mx6 3.10.17 (are all drivers ported?)
Is it reasonable to use libcec instead of imx-lib?

I also received a configure error of ffmpeg during xbmc compile - but ECANTPARSE. A hint how to figure out what's wrong would be nice.

I used the dora branch as hinted for xbmc - is it sane or is daisy reasonable?.

Thanks for any help.
