The other real problem is that Linus Torvalds has already said that
he will never ever in a million years accept a patch which attempts
to do such a thing, so you'd have to fork the kernel to do it.
According to Linus, architectures are either big or little-endian,
not both. A sane position considering the syscall ugliness you
mention...
