NanoBSD Build Failure

I am attempting to rebuild nanoBSD on an AMD64 system, using the same 
config file I used a couple years ago on a 32-bit system.

The target system is a TS5700 with an AMD Elan SC520, currently running 
nanoBSD from FreeBSD 6.2-PRERELEASE #0: Sun Oct 15 16:25:50 PDT 2006.

 From dmesg:
CPU: AMD Enhanced Am486DX4/Am5x86 Write-Back (486-class CPU)
   Origin = "AuthenticAMD"  Id = 0x494  Stepping = 4

The buildworld part finished Ok.  The gcc arguments seem OK for a 32-bit 

Buildkernel fails:

 >>> Kernel build for MYKERNEL started on Sun May 20 19:36:28 PDT 2012
mkdir -p /usr/obj/nanobsd.TS5700//usr/src/sys
 >>> stage 1: configuring the kernel
cd /usr/src/sys/amd64/conf; 
  config  -d /usr/obj/nanobsd.TS5700//usr/src/sys/MYKERNEL 
/usr/home/tomdean/nanoBSD/MYKERNEL: unknown option "I486_CPU"
*** Error code 1
1 error
*** Error code 2
1 error

Any ideas?
