Well, the irritating thing is that Intel uses different cpuids for
different steppings of the same model, e.g. 0x06D6 for the B-1 stepping
of the 723, and 0x06D8 for the C-0 stepping. :( See the doc at:
http://www.intel.com/design/mobile/specupdt/302209.htm
Either we should be able to detect multiple cpuids per model, or else
introduce different steppings for the fq_info structs, e.g.
pentium_m_n723b1 and pentium_m_n723c0. I'm not sure if different
steppings can also have differing operating points.
