I was going though some old 4xx kernels I have and found an

it never made is out was the hacking we did to make it work.  So I
propose that we modify the kernel/Makefile to use ppc4xx_idel.o instead
of idle.o when 4xx is configured.  That way we have a clean
implimentation for 4xx idle functions and not touch the generic ppc idle
file.  The function names would not change.

Rather than replace the whole idle loop, I would allow for
sub-arch/processor specific code in the idle loop.  Perhaps move the
power_save routine into the platform code?
