Nice! It'd be great to have the magical 20 lines of assembly put into some semi-understandable c.

hmm, I don't know x86 that well, but I did look at your [RFC][PATCH 8/8] Final i386 Relocation and I don't understand it fully. To make sure, is it possible for you to link at address X and run from address Y directly from flash?

Ah, I know understand what you are trying to achieve - No, my code does not allow for in-flash relocation.
My code processes the ELF relocation structures rel.got (which has pointers into .got), got.plt (which is where the location of .got is retrieved at run-time), rel.dyn (pointers into other sections other than .got), .dynamic and .dynsym
I must admit, I do not know why there are so many sections which need to be patched - I originally thought that only .got would need modifying, but the rabbit-hole is much deeper
Regards,
