I haven't tried it, but I'm rather unsure that the tradition dummy function
trick would work.

Your only alternative, I believe, is to patch gcc to support sections as an
__attribute__, put everything you need to lock in a single section, and lock
the whole thing.

Patches (including a pre-recompiled :) binary) and instructions for using and
locking sections can be found at Alaric B. William's web site:
