Do you have DHCP helpers for your normal DHCP server or the WDS server itself? My experience is that you need it for WDS itself (as well as normal DHCP server), although I admit I could be confusing that with old RIS. That came to mind because of the indication of it not working on different subnets. If you are already setup that way, I don't know of anything else right off.

The client gets the DHCP settings in its subnet, and then tries to communicate with the WDS server. If that WDS server is in a different subnet than the client, the tftp request fails. It probably doesn't help that the client, DHCP server and WDS server are all on different subnets. In fact, placing the client and the WDS server on the same subnet fixed the problem.
