Well, I think we can safely say that its something that's only
meaningful in 32/64-bit mode, so we aren't constrained by the real-mode
address space.

One of my goals in this project is to make the boot image, in some way,
completely define which memory it needs it get started.  That means that
the boot loader can either place things knowing they'll avoid the boot
image and/or definitively know that the image is unloadable.

So I don't think its strictly necessary to pre-define what memory this
object can use, since I think it can be safely determined dynamically.

That's a method of defining the memory space.

I think the current definition is suitable for entering at the 16-bit
entry point.
