    My Intel P150 (Overclocked to 166MHz) also shows up as a 75+

    processor : 0
    vendor_id : GenuineIntel
    cpu family : 5
    model : 2
    model name : Pentium 75+
    stepping : 12
    fdiv_bug : no
    hlt_bug : no
    sep_bug : no
    f00f_bug : yes
    fpu : yes
    fpu_exception : yes
    cpuid level : 1
    wp : yes
    flags : fpu vme de pse tsc msr mce cx8
    bogomips : 66.36

    It's definitely a 150 as it's got all the right markings on the top. (And if it
    was a 133 I'd have no chance of running it at 166, even with the heatsink and
    fan from one of those old Metal-top P90s I've got ontop of it)

    Model name is taken from the Model number - options are:
    (From /usr/src/linux/arch/i386/kernel/setup.c)

    Model 0 "Pentium 60/66 A-step"
    1 "Pentium 60/66"
    2 "Pentium 75+"
    3 "OverDrive PODP5V83"
    4 "Pentium MMX"
    7 "Mobile Pentium 75+"
    8 "Mobile Pentium MMX"

    So basically you're going to get Pentium 75+ unless you have a laptop, MMX or a
    really old P66 or less. The only thing that's going to change is the stepping,
    which is a bit like a version number.
