 I added i386 binary compiled from 4.4BSD-Alpha source.

 Boot with bochs works rather well. qemu-system-i386 also boots, and
NIC (NE2000 ne0) works good, but kernel prints many "ISA strayintr" messages.

 I got many useful infomations from below 2 sites:

  "Fun with virtualization"  386bsd bochs qemu
  "Computer History Wiki!"
                                         Installing 386BSD on BOCHS

 First time, I tried to compile i386 using 4.4BSD final (1995) source,
patching many many pieces from 386BSD, NetBSD, and else..
but then, I felt "Well, we have BSD/OS 2.0, NetBSD 1.0, and FreeBSD 2.0
those are full of good improvements.."

 So, I changed target, and remebered Pace Willisson's memo in 4.4BSD
(and in 4.4BSD-Lite2 also) sys/i386/i386/README:

  "4.4BSD-alpha 80386/80486 Status"  June 20, 1992

that file says "can be compiled into a fairly usable system".
yeah, needed chages not so small, though.
