Whatever GPU the Apollo has, it already has the drivers for it installed. They will already expose all the capabilities. There aren't going to be any new drivers that somehow increase those capabilities (except perhaps optimize the behaviour so that certain things are slightly faster).
Its possible I am misinterpreting what you are saying, so maybe you can tell me what gave you the impression that there would be new 3d drivers for the i5800?

 

it's for spica not i5800
