Do you mean that it calls dest->vtable->blit_from_system() instead of 
dest->vtable->blit_from_memory()? If so, I think you should provide the 
blit_from_system method and, more generally, all blit methods of the vtable.

See for example the X11 driver (src/x/xvtable.c) that doesn't support system 
bitmaps either. Note that exunicod uses system bitmaps and, AFAIK, runs on 
every gfx driver so providing all methods seems to be a requirement.
