Cross-compiling a kernel module?

[Martin Galvan]

Hi everyone! I'm trying to cross-compile a simple Hello World module for
the A10 Cubieboard (which is ARM/Allwinner10 based) but I'm not sure of how
to write my makefile. What I'm using to test it (on an amd64) is:

KMOD=hello
SRCS=hello.c

.include <bsd.kmod.mk>

I've been browsing the mailing list a bit and so far I've found a way but
it involves rebuilding the whole kernel, and I just want to compile this
module to load/unload in runtime.

Also, before you answer this: try and be as specific as you can, since I'm
kind of a newbie at this. Stuff like where should I put/look for files, run
commands, etc would be appreciated.
