OK, now I made some more tests, the system failed while reading ld-2.3.2.so,
here is the network dump on the NFS server:

It goes further reading this file and at the end:

Well, we can call it SPROTCH! It seems to crash. I suspect something
incompatible between a 2.4 kernel and something here, but I can't find a way
to build a 2.4 compatible NFSroot. Any ideas are welcome.
