I dont think so, but basically to support 9x, Kixtart needs some extra support DLL's, and it needs an RPC service running on the domain controllers ... So kix32.exe has the extra "layers" of code, to talk to the DLL's that talk RPC to the service. Thats my take on it anyways. All this RPC stuff makes up for the fact that lanman services on 9x is domain dumb. (Anybody?)
