Stable from 2003.10.07.00.00.00 also works.

The only commits between then and the broken kernel are:

  Edit src/release/sysinstall/Makefile
   Add delta 1.92.2.23 2003.10.07.06.59.19 ru
  Edit src/sys/conf/options.i386
   Add delta 1.132.2.20 2003.10.07.16.58.53 nectar
  Edit src/sys/conf/options.pc98
   Add delta 1.103.2.18 2003.10.07.16.58.53 nectar
  Edit src/sys/i386/i386/pmap.c
   Add delta 1.250.2.22 2003.10.07.12.34.37 nectar

My bet would be the pmap.c commit.  Anyone?
