Hummm.... these symbols should only go in if you config KALLSYMS_ALL. Are you sure your configuration doesn't have KALLSYMS_ALL enabled?
If it does, it seems like the correct behavior to include all symbols if you specified that you wanted _all_ symbols :)
By the way, there is a completely different version of scripts/kallsyms.c in -mm that you might want to look at. It will probably go in after 2.6.13 is out.
