These CPU's do not have there an letter whereas the Mobile CPU has an M. So there seems to be a need to update the intel_ips.c in order to recognize the CPU's with brand strings 'Intel(R) Core(TM) i7 CPU 610 @ 2.53GHz' and 'Intel(R) Core(TM) i5 CPU 520 @ 2.40GHz'. I have prepared therefor following patch:

Yep, that's fine with me, thanks for the patch!
