Can you try with just -mno-sse2? I'd like to litter the compile command line as little as possible.
I had this issue a while back with my Athlon-XP box (http://lists.freebsd.org/pipermail/freebsd-current/2004-November/042127.html). Note that I would get instant reboots with CPUTYPE?=athlon-xp, CPUTYPE?=p3, and CPUTYPE?=p2. However, it worked fine with CPUTYPE?=k6-2. I think you are right to be cautious and disable anything that uses FP registers.
I remember that problem but I don't know why I don't experience it, since I also use CPUTYPE=athlon-mp on my home desktop. I suspect the problem is SSE2 usage, which the Althon {X,M}P doesn't support.
Huh. That didn't fix it for me. I manually merged the sys/boot/i386/Makefile.inc and sys/boot/i386/boot2/Makefile changes, added CPUTYPE?=athlon-xp, rebuilt world and kernel, and rebooted. Same behavior. Oh crap -- I just noticed the sys/conf/kern.mk patch.
Rebuilding kernel...
