Creating Mac Computer Records in OD (Magic Triangle)

My Macs are being upgraded to Leopard. My Mac servers are running Leopard already. All my Mac desktops are bound to AD 2003 and will soon be in OD too (for the purpose of managing policies on the Macs via MCX) Enter the "Magic Triangle". It seems to me that (at least prior to 10.5 Leopard) the process of binding a Mac desktop to OD (and the associated back end Administrator work required in WGM for user management - i.e.; adding the Mac by MAC address etc) has been tedious, clunky and prone to human error. Good news (I think): I have noticed by accident that I was unable to add a Mac computer in OD if the same computer name already exists in AD. This is good right? I mean, I no longer have to manually add a computer object record in OD for all of my 200 Mac desktops. But... Bad news: It looks to me that WGM STILL needs to have each Mac desktop computer's MAC address (i.e.; Ethernet ID) added manually before MCX policies can be applied. Can anyone confirm this please? Do I still need to add each Macs MAC (Ethernet) address to their corresponding OD computer record? Apple doesn't indicate that you can now add Mac computer records into OD by using the existing AD computer record. I would love to NOT have to mess with manually adding each Mac's unique name and MAC (Ethernet ID) address into WGM. Can anyone confirm or comment on the observations and questions I have please? Thanks
