With the older one i have some problems with get all required virtual console etc drivers to compiled to kernel to make Xfree 4.4 happy. Ok, now there looks a like to be icecube_5200_CoralP_defconfig It is just somehow dificult to find all new files appearing to tree ...... May be it is worth to try use QT with X11 server instead using embedded qt direct to fb device. In older driver it was anyhow much better to use embedded qt direrctly.
