It's probably easier just to download this from someplace like mvista.com.

There should be sufficient options to the compiler that wouldn't
require rebuilding. I suspect telling it to use a 603 core with 405
instruction scheduling will make it work. Actually, just a 603
will make it work, the additional scheduling hints may improve
performance.
The bigger challenge is the kernel mofication necessary to properly
context switch the FPU on this part.

You are working with a really old kernel. Find a newer one. I would
recommend the 2_4_devel tree for what you are doing.
