On a 286 or higher the right answer is quite simply to run in 286 protected
mode - its not _that_ hard to do.

EMM is what you need for 8086 - paged memory banks. Generally people used
loadable DOS drivers so you'd need to dismember those to see what they
used for bank switches (or run them in DOSemu and log port accesses). EMM
as a banked disk cache, ram disk, swap is perfectly sensible
