# Ok, theory of what we are doing is this:  modprobe from modutils
# later than 2.4.21 have hardcoded 'above' and 'below' stuff that
# cause generate-modprobe.conf to generate a /etc/modprobe.conf with
# invalid (linux-2.4) modules in it.
#
# Now, one solution is to only use modutils-2.4.21, but then we might
# cause issues for users that still use 2.4 kernels, as later modutils
# might fix things ...
#
# Solution:  build modutils 2 times, once 2.4.21, and install insmod
#            as /sbin/modprobe.conf, and second time build current
#            modutils as we would.  Then we tweak generate-modprobe.conf
#            to rather use /sbin/modprobe.conf to generate
#            /etc/modprobe.conf ...
