Just an idea... you did set the "next-server" option in dhcpd.conf,
didn't you? Etherboot relies on its presence, which had been there by
default for ages, but the most recent dhcpd will not send it out if not
explicitely configured to do so. Try entering
	next-server 192.168.1.1;
in your dhcpd.conf and see if that helps Etherboot to find a DHCP
server.
