Right now, loading modules from the loader is supposed to be painfully slow, at least in many situations. dougb (IIRC) added the kld_list rc.conf variable so that modules could be loaded once the machine is up, which proceeds at a much more reasonable pace. This seems to be what Adrian is alluding to with '"fixing" of loader to cache metadata to make the reads faster'. -Ben Kaduk
