I have an i386 system working:

FreeBSD d820.flick.local 8.2-PRERELEASE FreeBSD 8.2-PRERELEASE #2
r216091: Wed Dec  1 18:06:20 CST 2010
root at d820.flick.local:/usr/obj/usr/src/sys/D820  i386

Just built the kernel and ran through some tests on the DTrace wiki page.

Incidentally, I had a tough time on my system running HEAD built with
clang. DTrace simply would not run properly until I built the kernel
with the base gcc. It was as if the kernel and userland were not in
sync, no matter what I tried (even netstat didn't work). Maybe you
need to clean EVERYTHING, checkout a clean source tree (if you've been
mucking around in there), and rebuild and install kernel and world.

I wish I could help more, but I'm still just a newb in a lot of respects...
