Dear Wolfgang

Thanks your for spotting my errors. I should have rechecked this patch before 
submitting it, as it was based on a outdated script. Please review the 
attached patch again which is based on a script which actually ran and 
produced a running kernel.

I would also thanks you for providing the ELDK. It was really a lot easier
to setup the ELDK once I switched from my PPC PowerBook to a MacMini. I can 
really recommend it.

The only addition to the ELDK I made to run xeno-test was to copy my 
Debian /usr/bin/which to the rootfs.

Best regards
