Okay, I went completely bonkers and tried it :) The diff below is needed
for a NetBSD/i386 host.
It booted FreeDOS without problems. I didn't have much time, but I
also tried booting a NetBSD install floppy. This bombed out at
some point, with "Panic w/ abort_code=1", which appears to have
come from:
Core was generated by `plex86'.
Program terminated with signal 11, Segmentation fault.

1658 case 1: *value = *(unsigned char *)(ctx->base + ctx->offset); brea
(gdb) print ctx->base
$2 = (void *) 0x48158000
(gdb) print ctx->offset
$3 = -1072691907
ctx->offset seems to have a ridiculous value.
I don't have time to look at this myself, unfortunately.
Anywhere, here's that diff.
