I manually compiled a kernel from source and after applying the mentioned patches (http://people.freedesktop.org/~zhen/snb_desk_suspend_0323/).
It did not work in my case (P67, external GPU), probably because the patches are related to an Intel video driver (i915).
Maybe this is helpful for someone with H67 board (uses Intel video driver).
