hints are either compiled into the kernel, or are loaded into the
kernel environment by reading /boot/device.hints.  There's nothing
really magical about it.  You could put all your hints into
/boot/loader.conf if you wanted...  If you compile them directly into
the kernel, the loader can't help...
