I had the exact same problem with CPUTYPE?=athlonxp on an i386 system 
several months ago:
http://lists.freebsd.org/pipermail/freebsd-current/2004-October/040493.html
http://lists.freebsd.org/pipermail/freebsd-current/2004-October/041981.html
http://lists.freebsd.org/pipermail/freebsd-current/2004-November/042127.html

I've just been running without CPUTYPE defined as I didn't know what 
steps to take to debug it and didn't get a response to help.

I can test and debug this if someone will help me out.
