One the 405 processors, with the endian bit set, the data is will be
true little endian.

well, this is in the context of a multi-CPU type (x86/ppc, sparc/ppc,
ppc/ppc, mips/ppc) shared memory multicomputer.

when dealing w/ direct mapped, shared memory, uniformity of endian-ness
makes many multicomputer problems easier to solve.(not to mention easier
for the customer to program...)
You are aware that a PPC in little endian mode is merely tricking with the
low order address bits, but does not actually lay out its data in a little
endian fashion in physical memory?
