I tested on vanilla kernel 2.6.36 but I need always to disable/enable
logical cpu on suspend/resume.
I think that it is a kernel related problem cause i5/i7 family seems to not
be full supported on linux kernel (just see turbo boost and C*-state)

hope that this annoying problem will disappear as soon as possible...
