Two different i386 machines at:

FreeBSD memory.visualtech.com 9.0-CURRENT FreeBSD 9.0-CURRENT #10: Wed Feb 24 
08:28:22 EST 2010     root at memory.visualtech.com:/usr/obj/usr/src/sys/MEMORY  
i386

The devel port you linked to works fine here now where as I was getting the 
errors you described above previously.  Great work!
