from Bogomips mini-HOWTO:

  As a very approximate guide, the BogoMips can be calculated by:



       System                 BogoMips                          Comparison
       Intel 8088             clock * (0.004 plusminus 0.001)    0.02
       Intel/AMD 386SX        clock * (0.14  plusminus 0.01)     0.8
       Intel/AMD 386DX        clock * (0.18  plusminus 0.01)     1(definition)
       Motorola 68030         clock * (0.25  plusminus 0.005)    1.4
       Cyrix/IBM 486          clock * (0.34  plusminus 0.065)    1.8
       Intel Pentium          clock * (0.40  plusminus 0.035)    2.2
       Intel 486/AMD 5x86     clock * (0.50  plusminus 0.01)     2.8
       Mips R4000/R4400       clock * (0.50  plusminus 0.015)    2.3
       Nexgen Nx586           clock * (0.75  plusminus 0.010)    4.2
       PowerPC 601            clock * (0.84  plusminus 0.015)    4.7
       Alpha (all CPUs)       clock * (0.99  plusminus 0.005)    5.5
       Intel Pentium Pro      clock * (0.99  plusminus 0.005)    5.5
       Cyrix 5x86/6x86        clock * (1.00  plusminus 0.005)    5.6
       Intel Pentium II       clock * (1.00)                     5.6
       Mips R4600             clock * (1.00)                     5.6
       Alpha 21264            clock * (1.99)                    11.1
       AMD K5/K6              clock * (2.00  plusminus 0.010)   11.1
       Pentium MMX            clock * (2.00)                    11.1
       Motorola 68060         clock * (2.01)                    11.2


66 for p166 and 447 for p225mmx seems to be fine

OK
