It looks like the code has atrophied.  Modern Linux kernels don't have
the /proc/ksyms file its looking for ... so it never moves on to the
stage where it looks at the System.map files.  Lemme go take a closer
look, see if this is straightforward to fix or not.  It may be simpler
now, as we have /proc/kallsyms which looks like its got everything we
need here.

cheers.
