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.

> - make.conf

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

> - kernel config

"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.
