There is one thing missing: the device has to be created with D3DRENDERSTATE_ANTIALIAS flag set, otherwise it won't work and the AA won't work with anything 2D based (textures, images), just polygons.
Problem with this "antialias" is that it isn't like the new one. It only has an on and off state, you can not set it to anything more specific, thats DX8+ only.
So if the drivers aren't set accordingly it will still fail
