Are you sure you want to do this???  The intsenses stuff in sandpoint_setup.c
is the way it is for a very good reason.  Can you send me your patch so I can
take a look?  Also, can you send the switch settings that you are using.

I think that your sandpoint-specific boot head.S or somewhere else like that
would be a much better choice than the ppc-generic decompress_kernel routine.

Let's hold off on this until people who have sandpoints can take a look.
