I see that ld has some support for overlays, perhaps we can use that?
The overlay support is basically just another way of manipulating the run-time addresses of the code at build time. Unfortunately, it can only specify static addresses, and I don't think there is any safe static address that can be used (outside of 0xc0000-0xfffff).
Is that not useful? We can push, say the IDE and virtio drivers to overlay the same address range in the e/f segments, and have the stubs pull them in as necessary.

I have a truly marvellous patch that fixes the bug which this
