Cool. New useful tools are always nice. Where can I download it/look at
its source code?

May I suggest that you run your tool against a more recent code-base, such
as the lastest stable kernel (atm 3.7.6) or the latest 3.8-rc kernel
(currently 3.8-rc6) or a daily snapshor of Linus' kernel.
That may gain you more feedback from people.

I'd suggest, that a more useful way of getting feedback would be to run
the tool against a more recent (relevant) kernel source and then submit
actual patches attempting to *fix* the problems you find. That would be
more likely to get peoples attention - and would also potentially result
in some nice fixes being merged.
