I can't speak for the acceleration issue, but I am pretty sure that 32
mb of RAM is plenty for running an X-based GTK on the Xephyr X server.
Even 8 years ago I ran GTK on X11 on a 32 MB ram handheld computer using
Kdrive, the forerunner of Xephyr.

Certainly I don't see how Xephyr + GTK is going to use very much more
ram than DirectFB backend + GTK.  Keep in mind that the GDK layer in
DirectFB has to implement many of the windowing primitives itself that
X11 provides, so the savings provided by DirectFB in the memory usage
department would appear to be nil.
