I wasn't but I'm now. At first I haven't copied/used directfbrc. After
your post I copied it and I received the following error(s).
(*) DirectFB/Core: Single Application Core. (2007-12-13 17:35)
(!) Davinci/Driver: FBIO_GET_TIMING failed!
--> Invalid argument
(*) DirectFB/Graphics: Generic Software Rasterizer 0.6 (directfb.org)

I rebooted my kernel passing 112M. However, driver still refuses to
work. I also re-compiled directfb with option --disable-fbdev. The only
thing is remaining sawman. I thought default manager would be fine, am I
mistaken?
Thanks,
