Well afaics, nfs works around this issue by having fs/nfsctl.o always as a builtin and abstract the calls through a file system using read/write. That would be Ben's idea again, i.e. not actually using a system call. The only widely used module that I'm aware of ever implementing a system call was the TUX web accelerator that that used a hack in entry.S and its own dynamic registration.
