Nobody (or at least most of us) don't even understand what exactly the
purpose of your patchset it. Can you try to explain what you're trying
to achieve?
Also, you should clean things up, put platform-specific things where
they belong etc. You really must review your implementation from an
architectural point of view. If you have questions, ask here first. In
most cases a patch describes things better than a thousand words, but it
is certainly not the case here. ;)

Luca.
