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.
