No, and there's not likely to be one anytime soon (unless you do it).
NetBSD has ports for a couple of ARM920T designs, which do have an MMU.
(I think they've recently popped a port for the Cogent CSB337, based on the
Atmel chip.)
The general feeling seems to be that without an MMU and the added features
of memory protection it provides, the heavyweight process-oriented UNIX
kernel doesn't really offer much advantage over a lighter-weight solution
like RTEMS or eCos. The uClinux gang disagrees with this assessment,
obviously, so you do have that choice as well.
