I think this should be fixed by recent changes to the atkbd driver in HEAD
by Jung-uk Kim.  I'm not sure if there is a newer snapshot built yet, but
perhaps you can try booting a HEAD kernel into single user mode (will probably
blow up due to not liking /sbin/init) on your i386 world (would need to
use a cross-build (so 'make TARGET=amd64 kernel-toolchain; make TARGET=amd64 
buildkernel', etc.) as a test?
