I have written this program taking example from SMARTSHADER Blur.pss.
should work on all dx9 cards.

gpuPeteOGL2.vp:

!!ARBvp1.0
OPTION ARB_position_invariant;
MOV result.texcoord[ 0 ],vertex.texcoord[ 0 ];
END

gpuPeteOGL2.fp:

!!ARBfp1.0

PARAM offset = program.env[1];
PARAM const00 = {0.25, 0.25, 0.25, 0.0};
PARAM const01 = {0.5, 0.5, 0.5, 0.0};
