Well, FBIO_GET_TIMING seems to be not supported in your kernel.
In DirectFB, initially, the screen size was fixed, later it was queried
using FBIOGET_VSCREENINFO,
and currently it is queried with the FBIO_GET_TIMING which is failing below.
I'm not sure if this will lead to further issues, but I noticed that 1
failure case is not
handled properly, so you might want to try the following patch:
diff --git a/src/core/layer_context.c b/src/core/layer_context.c

Otherwise, you should either revert the fix done on davinci_screen.c
http://git.directfb.org/?p=core/DirectFB.git;a=commitdiff;h=d261c76eb8c8a53bc8e2132f6b8905b58a01340d
or update/patch your kernel.. There are some DaVinci kernel patches
floating around..
