If no texture is set, it behaves like D3DTA_PREVIOUS. Perhaps for alphaarg it behaves similarly if there is a texture, but it has no alpha. If that is the case, then I think it matches what you need for D3DTBLEND_MODULATE. Otherwise I think a private value like your D3DTOP_DX6MODULATE is the only way.
So I'd say test how D3DTA_TEXTURE should behave, maybe we implement it incorrectly at the moment.
