IIRC, beginning in the 2.6 kernel series, there is an
... interesting ... new procedure
where the program derived from "scripts/modpost.c"
(found in the root of your kernel tree) must be used
to build a module header using your kernel's Module.symvers
file and the your main module.o file, The resulting file
is subsequently linked using "ld -r" with your otherwise
normal module.o file(s) to yeild the module.ko file.
