David Frascone <dave@frascone.com> noticed two problems. First, modprobe was

trying to call 'insmod -q', which wasn't supported.  Secondly, when modprobe
was fed blank lines from modules.dep, we ended up calling xstrndup(ptr, -1),
which with suitably bad results.  David provided a patch to catch the blank
lines, and I have added insmod -q support.  So modprobe should work again.
