NFS seems to work but considering what I saw in tcpdump it uses TCP instead of UDP. I have not yet found out why NFS seems to default to TCP on Cell (the man-pages claims that UDP is the default). If I explicitely demand to use UDP it indeed does not work at all. Again if I use tcpdump on both sides, I see that the NFS-server claims to send out IP fragments containing the UDP datagrams (larger than MTU). The NFS-client does not see any of these fragments. Using the patched spidernet module makes NFS work like a charm.
