Running with --all-symbols this seems to work fine.
I suspect the change in the kallsyms compression algorithm between 2.6.9 and 2.6.10. It added 3 new symbols and I am not convinced that they are being processed correctly by scripts/kallsyms.c. Apply this debug patch, tar .tmp_kallsyms* and send the tarball to me.
