Has someone tested this with kexec/kdump? Thats why the origional patch was created, because when kexec loads the kernel at a different physical address, the relocations messed with the module crc's, and modules couldn't load during the kexec boot. Assuming that kernaddr_start gets set appropriately during boot, using PHYSICAL_START should be fine, but I wanted to check, and don't currently have access to a powerpc system to do so.
