I don't know if that'd work, since the w/h/vw/vh parameters will have an 
effect on the selected driver. Unless you want to do
int detect_gfx_driver(card, w, h, vw, vh);

Pure DOS, probably. But I don't know whether DOS emulators, or Win9x 
will allow that. It would depend on the driver since some of them 
require banking and others have VRAM limits (VGA). And if you could get 
the whole VRAM block in DOS, what was the point of vw/vh in the first place?

How does SDL handle virtual screens/video surfaces? Does it just not use 
them for X11 or non-Windows platforms?
