Hello everyone, as I've gotten no reply whatsoever to my message three weeks ago, I just wanted to ask whether anyone has any experiences at all with that Intel board (not the most obsure mainboard in the world) and DirectFB? I'm still at a loss as to how to get a decent display w/o using the slow-as-hell vesafb plus software renderer.
