Has anyone ever seen a machine with "negative addresses", that is, one
where the address space is -2**31..2**31-1 rather than 0..2*32-1??
Any thoughts on what the problems with such a scheme might be (or are)?

Why ask such a question, you ask -- well, I'm trying to remove unsigned
arithmetic from WM, and as far as I can tell, the primary (only?) use
of unsigned arithmetic is for address computations. Soooooo...
