You don't need to change the defaults at all, you know. It's not like
you're likely to *notice* any difference. And the specific answers
depend on the version of FreeBSD you are running.

"man make.conf" and search for "CPUTYPE". It will point you at a
sample or default configuration file.

"man 5 config" and search for "cpu". You'll want the 686 version
according to that dmesg output. On -STABLE (at least; I think this is
true on all versions, but I'm not sure), that is I686_CPU. In any
case, it will already be in your configuration file (or GENERIC), and
you just need to remove the others in your config file.
