I'm not sure what the problem is. My dhcpd.conf looks like this:

host imac {
  hardware ethernet 0:d:93:48:c2:86;
  filename "loader.ppc64";
  option root-path "/usr/netboot/powerpc64";
  next-server 10.0.1.37;
}

Also, options SMP isn't in GENERIC, so you may want to add that for full 
support of your machine.
