um ... no, it wouldn't.  while testing it would theoretically tell me if
it worked for *me* in *my* particular configuration with *my* specific
config file, it wouldn't answer the wider question as to whether this
should be expected to work under all circumstances. demonstrating a data
point size of one does not constitute a proof.

what i was after was a more general answer, perhaps related to being
dependent on kernel config options, module versioning, something like
that.  or, OTOH, the simple answer that, "yes, you'll be fine" would also
be acceptable.

all of us have, at one time or another, fallen into a habit of doing
something a particular way, only to get burned by it some time down the
road and to eventually learn that we've just been lucky all this time.

just playing it safe, that's all.
