What you are doing sounds a lot more similar to the DirectFB
approach. Perhaps you should check out GTK+ for DirectFB instead:

 http://directfb.org/gtk.xml

Actually I wonder if we need yet another windowing system on top of
the Linux framebuffer device. Did you look at DirectFB before? It is
very far already and perhaps it would be better to join efforts.
