i dug this content:

      if exists dhcp-parameter-request-list {

             # Always send the PXELINUX options (specified in
			hexadecimal)

             option dhcp-parameter-request-list = concat(option
dhcp-parameter-request-list,d0,d1,d2,d3);

      }

perhaps try in hex?  i don't know if that is required just in
dhcpd-scripting, or what.  not many references for that option.
