fragment combiner program


Is there any possibility to use a fragment program together with a fragment combiner program, as it is mentioned in early revisions of the NV_fragment_program spec (probably undocummented, provided only for compatibility)?
A solution which works only with older drivers would be perfectly okay for me.

Thanks, Helmut

There is the EXT_cg_shader extension which enabled CG shader support using OpenGL Shading Language Interface. Maybe you can use register combiner and texture shader using this interface.
