Wow, thanks for the precise reply , I did tried something like your sleep method, but, as I said before, it doesn't work for me, I did not know instead about the Errata thing and now, I verified and it's 0x0 so there must be smth wrong and there is still a chance to fix my sleep.
I will try everything on a clean install with a sata disk ( now I am on IDE ) tonight and let you know .

About the pin configuration, I saw your dsdt.dsl and in my opinion we have the same data in the dsdt but you can always check here

As an alternative you can try walterav's pin configuration here

Both posts have also files attached try both kexts mine's and walterav's even if they seem equally .

Thanks again and good luck with the mic
