Great, but I'll be damned if I can find it. :)

I'll just point out that I'm doing this user-mode port with a slightly
different angle.  It's might be duplicated effort, but hey, this is for
fun.

My Linux/a386 project is just like uml, but with a separate
CPU/hardware layer called a386.  I think this will make it easier to
port to other Unices, as well as make it easier to port other
operating systems to user-mode.  NetBSD/a386 is my next target when
Linux/a386 stabilizes.

See

and

(new locations; Jeff, please update)

I don't think ptrace() is in POSIX at all, so that is a huge problem.
