Roughly speaking directx6 and 7 are the same and your game is just operating in
that mode. DirectX 8 is very different and the main new feature are shaders
(pixel and vertex shader 1.x).

In OpenGL shaders can be implemented using ARB shader extensions
(GL_ARB_vertex_program/GL_ARB_fragment_program) and GLSL. The problem is that
the Geforce3/4 and Radeon 8500/9000 only support GL_ARB_vertex_program. They
don't offer enough functionality to support GL_ARB_fragment_program which is
used for shaders. Both cards offer some other extensions called
GL_NV_register_combiners / GL_ATI_fragment_shader which can be used to support
pixel shader 1.x. We don't have code for this and adding such a backend is
quite a bit of work. All cards starting from the GeforceFX / Radeon 9500
support ARB shaders and even GLSL.

Unless someone stands up to add support for old cards, I don't expect anyone of
us to add it. As it is only for a very small group and picking up a better
videocard which offers GLSL is rather cheap. Unfortunately this is a WONTFIX.
