I've dropped this from my tree as I don't want to add these options,
only to have to remove them later on when it's found out that these were
a bad idea.

I don't want to create a user api that we have to keep around for
forever, and this would be such a thing (specifying how the kernel
probing works.)  For debugging, can't you just patch up your kernel and
test this out?  What's the real use of this?  Who do you want to enable
these?  And why?  What will you do with the information?

thanks,
