Hi Korey, I'm not the Ruby expert, but I think adding support for banked caches would be great. However, I wouldn't do it via address ranges, since in many cases you'd want to use low-order rather than high-order bits to select the bank.
I'll leave it to someone else to discuss how it *should* be done...
