It looks like /etc/rc.d/initrandom is no longer correctly checking for
whether the software generator is in use, so it tries to set sysctls
that don't exist. Those partiticular warnings look harmless. 

It might be that writing to /dev/random which occurs immediatly after is
causing the problem. Try commenting out the following:

		# First pass at reseeding /dev/random.
		#
		case ${entropy_file} in
		[Nn][Oo] | '')
			;;
		*)
			if [ -w /dev/random ]; then
				feed_dev_random "${entropy_file}"
			fi
			;;
		esac
