GTK+-DirectFB is only a solution if the graphics chips you are using is
supported by DirectFB. DirectFB has software fallbacks that allow it to
run on all kind of hardware, but if you want to use it on an embedded
device than you first need to make sure that the graphics hardware is
fully supported by DirectFB. If it isn't, and you don't have the
resources to develop a graphics driver for it, then you might have more
luck with other backends such as X11.

I agree with Sven's analysis and i add that, leaving out performance and resources consumption considerations, Gtk-DFB is a valid option only in the case a single/few applications are meant to be run on the considered device (tat was actually the case of the graphical debian installer). Otherwise, if many Gtk applications are meant to be run in a desktop-like scenario, the best option is still Gtk/X11 + Xserver or XDFB rather than Gtk/DFB + DFB due to fact that at GTK/DFB is not yet as mature as GTK/X11 in terms of implemented functionalities.
