I have revamped the patch, but the request for the IA32_EMULATION is still pending. I have now a solution for this which i had already implemented, but i need to do some tests.

Currently my latest version is for 3.10, but i think i can bring it to 3.13. I will do this next weekend and post the patch.

I am interested since i must port again and again to the next kernel version for my devices.
Your support will be welcome.

Stay tune until next week.
