Or more practically, a smart loader than could select a kernel image
based on arch and auto-detect to load the correct image. I don't really
think it matters much what mechanism is used.

What makes more sense is to pack multiple segments for different
processor architecures into a single executable package, and have the
loader pick the right one (the NT model). It could be used for
SMP and non-SMP images, though, as well as i386, i586, i686, etc.
