If you're interested in running V7 on x86, you should check out
the 286-port on the TUHS FTP site, as it was fully operational
until the author, according to his report, messed up the file
system code.
For a 32-bit Unix, the Quasijarus project would be better
starting point, as it is more seasoned as a 32-bit operating
system. The project project was started by Michael Sokolov, with
the primary goal of extending 4.3BSD-Tahoe to run on newer VAX
hardware. You can find the source, as well as the mailing list,
from the web page at: http://ifctfvax.harhan.org/Quasijarus/
Because NetBSD and especially GCC have long since outgrown all
but the most powerful VAX hardware, including my VAXstation
4000-60, I've been looking into the possibility of getting
Quasijarus to run on the machine - very slowly, of course.
I've only managed to hack the NetBSD kernel into running the
binaries properly - it should support 32V-ones as well, for
that matter.
I'm also interested in 386-ports of the classical Unix utilities,
but my kernel-side focus is on a brand new, non-portable kernel
written in assembly language for compactness and flexibility of
running, examining and debugging code that excessively picky
operating systems choke at - e.g. real- and kernel-mode code.

Did you make other improvements than XP cross-compilation?
