# Structure
#
# 1) Check if we have module unloading support
#    a) Look for /proc/config.gz first
#    b) Failing that, check uname -r and look in /usr/src/$ver/.config
# 2) If we don't have module unloading support, warn and explain what to do, try to run once
# 3) If we do have module unloading support, run as many times as necessary to get it working?
#    Or a set number of times?
# 4) Each run consists of checking if the module is loaded, rmmod'ing if necessary, applying
#    the new mask, reloading the module.
# 5) After each run, check if it took. If so, rock on. If not, keep trying, or run up to a set
#    number of times, then error out, give up and load the module anyway.
# 6) Stop is the same, but with the original mask
