Well, this sounds very much like your vmlinux is relocated to the wrong adresses, and then it's not surprising it doesn't work. You definitely want to change arch/i386/vmlinux.lds.S. I'm not sure if you actually want to change PAGE_OFFSET, but I don't see a fundamental reason why it should be needed, so I think you should try as-is.
