OK, we've finally solved the problem:
It was a bug in Redhat's module-verification-patch, which has been fixed
in kernel-2.6.12-1.1398_FC4 (and 2.6.12-1.1376_FC3):

- ---------- snipp! ----------
* Mon Aug 15 2005 Dave Jones <davej@redhat.com>
- - 2.6.11.5
- - Fix module_verify_elf check that rejected valid .ko files. (#165528)
- ---------- snipp! ----------

# diff
2.6.12-1.1398_FC4/BUILD/kernel-2.6.12/linux-2.6.12/kernel/module-verify.c
2.6.12-1.1447_FC4/BUILD/kernel-2.6.12/linux-2.6.12/kernel/module-verify.c

<       elfcheck(tmp < size - hdr->e_shoff);
- ---
>       elfcheck(tmp <= size - hdr->e_shoff);

With the new kernel openafs compiles and works like a charm.
