That is: in the way I called "certainly the wrong thing to do"?

I guess section "6.3 Symbols From Another External Module" from
Documentation/kbuild/modules.txt contains possible solutions to that
problem.

To get good answers it helps to quote the command you used and the
output (stderr and stdout) that this command generated.

Greg K-H wrote a booklet that explains most of the problems you've run
into in, I think, great detail: "Linux Kernel in a Nutshell". Perhaps it
is available for free on the interwebs (as its license allows that).

Anyhow, I'm running out of time here. I'll be glad to try to talk you
through setting up things properly (especially /usr/src/[...]
or /lib/modules/[...]/build), if still needed, next Monday.

Hope this helps,
