Actually, issue is not from 2.6.35, it is rather android's "udev" like system, that does not put msr in its own directory. Hence the change in order for powertop to support android. I agree it has to come in another patch. John, What I dont understand is how you disable MSR_CORE_RESIDENCY and MSR_CPU_RESIDENCY in this patch. It is done by not adding the Medfield model id to the checks to create "new class nhm_cpu" and "new class nhm_core" subsequently. It is in these two class implementations that msr registers related to core and cpu will be checked.
