I went to the MINIX BOF at USENIX last week. Andy T. said the
compiler supports only the small model, but MINIX supports 64K
text (code segment), 64K data (data segment) and 64K stack
(stack segment) (like "split I and D" on some PDP-11s).

If you have a cross compiler, you can generate programs that use
192 Kbytes (3 * 64K) of memory.  If the native compiler generates
something like the ".text" and ".data" pseudo-ops, it might not
be too difficult to hack the native assembler and native linker
to generate the "split I and D" object files.
