There are some tricks you can play. Notably, you need to trick auto*
tools into thinking it's an i386 system. I think setting UNAME_m=i386
does the trick there:

01:20:52 EST 2008 root@pflog.net:/usr/obj/usr/src/sys/PFLOG i386
I believe there is something else I'm forgetting that you need to do
to make compilation happy for some ports, but I can't recall them at
the moment.
Of course, things that expect to talk to an i386 kernel aren't going
to work, and you may have issues with things that use hand-written
ASM.
Try setting UNAME_m though and see if it helps. It might also be wise
to set ARCH=i386 and/or TARGET_ARCH=i386 in /etc/ports.conf.
