The choices for the cpu directive in the kernel config file, as described in config(5) and listed in src/sys/conf/options. (the only choice for amd64 is HAMMER), have nothing to do with the choices available for the CPUTYPE variable (which you may want to change to suit your hardware -- these are the architecture-dependent options available for the -march and -mtune directives of your compiler that are also recognized by bsd.cpu.mk), or with the cpu descriptions printed during boot. b.
