Cannot get 3D support with unified ATI drivers with Hercules AIW 9000

I've been trying to get the unified ATI drivers to work with my Hercules Prophet AIW 9000. After manual tweaking of the XF86Config-4 file (the one ATI made did not allow X to start) I've been able to get it to run, but I have no 3D nor any DRI support. Has anyone been able to get these drivers to work with this card? Any suggestions one might be able to give me? Regards, Pieter Hulshoff
