You'd still have to perform the VM86 calls, since one of the things they
do is generate a map of where the useable memory segments are. The
environment variable would be used later (at the same point where the
npx0 hack is) in order to cap Maxmem.
I like the idea of being able to say:
set console=comconsole
set maxmem=....
