It is how you call it. X server or Embedded QT graphics driver normally
works
in user level..

Yes, this was that i were using and in this one x-server was just
patched to fix byte order.

I should try this new one. 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.
