Can't yet comment on the real XCB patch as it's still baking, have to
get back to that later.

In the meanwhile I thought I'd mention I managed to manually compile
qt5 with xcb support against the master.
There were some hurdles on the way but I got at least the Qt widget
applications running on the X (run in the default matchbox window
manager of my image).

The QtQuick2 and consequently EGL/gles2 didn't at least yet work so great:

root at nitrogen6x:~/helloworld# DISPLAY=:0 ./helloworld
Qt Warning: Could not find a location of the system's Compose files.
Consider setting the QTCOMPOSE environment variable.
Warning: EGL suggested using X Visual ID 33 (RGB565) for EGL config 28
(RGB444), but this is incompatable
Unable to find an X11 visual which matches EGL config 28
Could not initialize EGL
