Ok, I've applied this to my tree.

I note that the physical BOOT_PCB addresses in the alpha setup.h file
might be useful for things like MILO in user space, but since I
couldn't even find MILO sources any more, I couldn't really check.

I suspect alpha is basically on life support and presumably nobody
would ever compile a bootloader anyway, so it's unlikely to matter.

If somebody does find any issues, we'll know better and we can ask
where the user space sources are that might use that alpha setup.h
