Yep hacking suser()'s idea of root's uid is an example of a trivial
modification, thats trivial to do.  What the other guy was on about - loading
new (non-loadable, obviously) modules into a running kernel is distinctly
non-trivial in comparison; hence my point that it depends on the mods you're
making.  Thats whay Im interested to hear the two ways.
