If you look at /usr/src/linux/README there is a section which explains
how you can use nm to look at linux/vmlinux, but the existence of this
file and it's correlation to the chosen kernel can't be assumed.  It would
be easier just to look at .config, but again this is speculative.  I
suppose there is a way of finding this out, and I am open to suggestions.

Good question.
