The Apple Partition Map will work with PPC and Intel Macs, the restriction comes when you try to install Lion on the drive with APM, it requires the GUID format. I even was able to boot my MBP Core i7 with a copy of Leopard on an external HDD and APM. This method allows different systems on one drive, handy for testing purposes. I have had trouble getting the format changed on the WD external drives you may have to do it multiple times till it sticks. It's not the HDD, it's the board in the enclosure.
