On some platforms, /dev/random and /dev/urandom used to provide different quality of random numbers-- FreeBSD simply uses Yarrow or a hardware RNG source if available.  Even if you disable it, it's likely to just fall back to OpenSSL's source of random numbers, which probably is /dev/random anyway....
