Access host PC memory from app1040 reference system (PPC440) on ml507

We have implemented the reference system as per app1040 (PPC440) on the ml507 board. This board is connected to the PCIe slot of PC running Fedora core 11 on it
Our question is, is it possible to access the PC host system memory (DRAM) from the PPC440 or by the local link DMA via the PLB bus? What is the memory address that we should give as the destination address when transmitting from PPC to PC host memory? Since the PPC or the HDMA is connected to the PCIe endpoint v300 on the PLB, how does the PLB address get translated to the PCIe address of the PC host system memory?
