Anyone can disassemble a binary and re-compile it. Understanding exactly how it works is another 
story entirely. I believe you would be in violation of the license if you distributed the 
de-compiled source, so what do you gain by doing this?

In addition, we are talking kernel code here. The sort of stuff where random compiler optimisations 
can cause catastrophic failures. Can you guarantee by doing this you are generating exactly the same 
code as you started with? I would certainly be loathe to trust the compiled binary.
