Oh, yes, section mapping is done in common gdb code.
Perhaps kld.c shouldn't call build_section_table, but directly call
bfd_map_over_sections with a custom variant of add_to_section_table?
Can you please share the patch?

Still, what about a small tool, elf(3)-base porgram or objdump+objcopy shell
script, that would set section addresses in amd64 .ko (relocatable object file)
similarly to how they are set in i386 .ko (full-blown DSO)?
Or is this too much useless hassle?
