Doh! This should have occurred to me.

Done. Got the same problem that led to rebuilding all this in the
first place. I hacked up gtk+-directfb's _gdk_windowing_init_check to
use layer 2 instead of DLID_PRIMARY (Matrox CRTC2) and then set the
pixel format to RGB32 with the following code:
#if 0
ret = DirectFB->GetDisplayLayer (DirectFB, DLID_PRIMARY, &DisplayLayer);
#else
ret = DirectFB->GetDisplayLayer (DirectFB, 2, &DisplayLayer);
if (ret == DFB_OK) {
DFBDisplayLayerConfig dlc;
DFBResult ret2;
dlc.flags = DLCONF_PIXELFORMAT;
dlc.pixelformat = DSPF_RGB32;
g_warning ("setting pixelformat to %x", dlc.pixelformat);
ret2 = DisplayLayer->SetConfiguration (DisplayLayer, &dlc);
if (ret2 != DFB_OK)
DirectFBError ("gdk_windowing_init_check: SetConfiguration", ret2);
}
#endif
but when the code runs I am getting:
(*) DirectFB/Layer: Enabled 'FBDev Primary Layer'.
(*) DirectFB/Layer: Enabled 'Matrox CRTC2'.
(chooser2:25340): Gdk-DirectFB-WARNING **: setting pixelformat to 401804
(#) DirectFBError [gdk_windowing_init_check: SetConfiguration]: Access denied!
Not sure what "Access denied" means in the context of SetConfiguration
however.

Can't wait until it does so I don't have to hack it to use the CRTC2
layer. :-)
OT: You know what would be really nice, but certainly outside the
scope of (gtk+-)DirectFB, is runtime binding to the GDK library.
If all gtk/gdk apps were linked to a generic libgdk which then
(based on some criteria at runtime) decided which libgdk backend
to use (X11, DirectFB, etc.) one would not have to keep the same
app linked differently for each graphics paradigm one wanted to
run it on.
