Okay. I suppose the only other option is to make "physical_start" a variable

PHYSICAL_START and this didn't look _too_ bad.

No can do. You'd have to make the kernel relocatable, and do load-time fixups. Very invasive.

Yes, that wasn't too smart. I believe in principe most of it _could_ be done via some pagetable trickery though, with the kernel still at a fixed virtual address?
