Sorry being late to reply, but I was out for few days.

I've not seen any code for Graff and that demo for sure don't run on
N800, but flash, we do some prototype here using it too.

Cairo, as suggested, will not be an option in near future, since it
does 32bpp graphics and the conversion will kill our hardware.

I'm working on Evas for embedded systems and have it working for
Maemo/Nokia N800 using software_16 (which I wrote with help of
rasterman), python bindings and even some examples (with source


you may also search for EFL on my blog history and see expedite
(benchmark) demo running.

all the code ({evas,ecore_evas,etk,ewl}/software_16, python-efl,
demos) is being done in e17 CVS, so code is already integrated and is
available under BSD license for those who care.

I work for INdT, thus our focus is Maemo/Nokia products. We have at
least 3 guys working with EFL, fixing bugs and writing tests and
prototype for our next version of Canola. But I know of Koen, Mickey
and Rasterman working with openmoko hw and they may report status on
this hardware (which I still don't have).
