No. An accelerated DX driver would be a normal driver from the first
group. The point about the second group is, that you use the OpenGL API
in addition or instead of the Allegro API. Maybe it shouldn't even be a
second group, but each driver simply could have the option to create a
window with an OpenGL context, if requested.
DirectX in any case should always be hidden from the user.
