Your frame buffer driver doesn't seem to support 32 bit modes.
Do you use rivafb? Looked at /proc/fb?
You could comment out the SetCooperativeLevel() call or strip out
the DFBCHECK embracement and call the application with
"--dfb:force-windowed". This way a window with ARGB format is created
and blended onto your whatever-bit-depth screen.
