Is that from a tarball or cvs?
DirectFB/gfxdrivers/unichrome/uc_overlay.h should be from 2005-02-27 or later,
so that there is my tiny patch included (see below - SetLevel()).

My epia system is gentoo based with kernel 2.6.7 and epia patch.
Last time I tested this box dfb worked ok.
My modprobe lines are:
modprobe cinergyT2
modprobe snd-via82xx
modprobe viafb mode=1024x768 bpp=32 refresh=60 TVon=0
and my /etc/directfbrc on this box is:
#mode = 1024x768
mode = 1280x1024
#pixelformat=AiRGB
pixelformat=ARGB
disable-module=cle266
which results in:
root # fbset -i
mode "1024x768-76"
# D: 78.653 MHz, H: 59.949 kHz, V: 75.694 Hz
geometry 1024 768 1024 1536 32
timings 12714 128 32 16 4 128 4
rgba 8/16,8/8,8/0,8/24
endmode

The only line that looks strange is:
[dfb] SetParams: action=IDirectFBDisplayLayer::SetLevel(int), result=Not supported! Failed: SetLevel()
