My bad here: I missed the '-r' in the first modprobe.

I am wondering if 'modprobe -q -n' won't suffice, as it is a dry-run
only, but will still search for the module? Unless of course, there's
something specific about '-q -r' that seems better still?

Could you please disregard this patch, and the other patch I sent:
will send out a new version soon.
