I've taken this one step further by also disabling any unused drive addresses in the BIOS. Many BIOS's spend as much time searching the universe for devices as FreeBSD does. It also may be a good idea to remove other unused devices from the kernel as well. The disadvantage to this is that every time you change your configuration you will need to rebuild the kernel. Hopefully that won't be that often.
