Have you tried Minix 2? It will run quite happily on an 8086 with 640kB of RAM, although it does tend to run out of memory if you do too much stuff. It might be able to talk to the Toshiba's EMS system for swap space, though.
Minix 2.0.2 as sooner will run on 8086/640k, even with TCP/IP. However it uses lots of memory for the kernel and basic programs (getty, sh,...) so it lets only a couple of 64k spaces for user programs.
In 2.0.3 (?) they included a swap mechanism... but it used even more meory, getting it unusable at all for 640k computers.
They said it will be a target for future releases, but it seems Minix3 is a higher prioirity now.
It'll give you a Unix-alike that while being rather slower than ELKS, is considerably more mature. (Dual-booting Minix and ELKS might be rather useful if you want to do ELKS development. It ought to be possible to cross-compile ELKS from Minix.) It's also got a big library of software designed to run in a split 64/64 address space, which means it should be easy to port to ELKS.
In fact, many of the user programs we have in elks are proted from minix by elks developers.
