Since OpenBIOS does not work with qemu-system-ppc64 due to lack of USB 
support currently I could only try with qemu-system-ppc with a G4 CPU.

So then I guess this patch cannot work then for newer ppc-s and I will 
have to get back to my older patch that moves the exception vectors from 
the beginning of RAM. I'll send that again instead for review.
