Umm... I think alpha was never implemented in DirectDraw. Am I wrong
about this?

Although the functionality for alpha was implemented in direct draw, it''s implementation never was added. Therefore these parameters won''t be of any use to you. In order to alphablend in direct draw you have to do the entire thing yourself in software.
