I don't remember how well it worked, but I'll provide the recipe
and associate files I was working on last year for the kernel modules.
Maybe they will have worthwhile hints.
There were three files, I see: the recipe, a Makefile replacement,
and a version-generated.h file. It's quite possible -- likely,
even -- that both of them (especially the Makefile) will have to
be modified for use with the new VirtualBox.
Unfortunately, I really have no recollection about what was special
about that replacement Makefile. It's been too long.
It's quite possible that this is completely irrelevant to your current
work -- I see that I never checked in my work, so it's likely that it
hasn't been tested in rMake.
