I guess you must feel desperate about this patchset getting into 
mainline and I'm sorry not to have looked at it for months.
Anyway, I got some time today and built everything from scratch again 
using the configuration you suggest in you 7/15 but for my board 
(nitrogen6x kernel and u-boot config).
First of all, everything applies and builds fine on today's master. Then 
everything I've tested is working fine:
- X (starting the X server with the xorg.conf from Yocto):
https://github.com/Freescale/meta-fsl-arm/blob/master/recipes-graphics/xorg-xserver/xserver-xf86-config/mx6/xorg.conf
- GPU libs with X back-end (test of turorial7). Plus I made sure 
building with fb back-end still works fine
- Qt5 with openGl, as I didn't what was the best test I've started a few 
binaries:
# /usr/lib/qt/examples/opengl/hellogl2/hellogl2
# /usr/lib/qt/examples/gui/openglwindow/openglwindow
# qmlscene TestCase.qml

In other words, everything runs great!
