netbooting Apple Xserves, not working since dhcp version 3.0pl1-9a

Ok, here is my current dhcpd.conf, and I have compiled dhcp 3.0.6 from
tarball source and using that I still cannot get the Xserve to netboot,
it looks like bootp isn't getting recognized as such, see
/var/log/messages below. Can anyone even confirm if they have netboot
working with Apple ppc64 Xserves with dhcp 3.0.1 or higher?
dhcpd.conf:
authoritative;
allow bootp;
ddns-update-style interim;
default-lease-time 30000000000;
option dhcp-parameter-request-list = 1:3:dc:dd:e6:e8:e9:ea:eb:ed:ee;
option mac-nc-client-unknown code 220 = string;
option mac-nc-client-id code 221 = text;
option mac-version code 230 = string;
option mac-user-name code 232 = text;
option mac-password code 233 = text;
option mac-nb-img code 234 = string;
option mac-apps-img code 235 = string;
option mac-machine-name code 237 = text;
option mac-version = 0;
option mac-user-name = "netboot";
/var/log/messages:

When it was working with the older dhcp version 3.0pl1-9a my
/var/log/messages would look like:
