Bitmap or stack based memory manager

I understand now. I am used to interpreting e.g. kernel addresses as virtual. For example, the Mobius kernel is linked at address 0xC0000000, and it doesn't care what physical address it uses. This makes sense to me, because it needs to use the physical address only at startup, and the virtual address the rest of the time. In fact, I don't need any identity mapping at all.
