Your patch might work on the A7V, but it does not on my A7V133-C. If I
modify the OEM string in the patch, it works. It may also be modified to
[...] "A7V-133", 7)[...] but then it probably won't work on a A7V...

As said in another post, the patch from the intel site also solves the
problem.

Rasmus
