I'm still interested with the directfb backend :)
It makes sense to use directfb when you need to precisely control over
how much graphical memory is allocated. For example X doesn't give that
kind of control. For more, you can have plenty of logs when compiling
directfb with traces, which gives you plenty of informations about how
things gets done at low level (under webkit/cairo/etc...).

Chris, if you have a better thing to use than directfb, let us know.
