Thomas Hogarth and I have done some work on running FFP models in GLES2, with his extended ShaderGen code. It appeared originally in his HogBoxLib: http://www.hogbox.co.uk/hogboxLib/hogboxProject.php
I am not sure how closely that repo is currently tracking his latest changes, so it might be best to inquire with him about the latest code.
