That works well until you change something that has side effects. Consider the Cyrix 5x86/6x86 chips. On the 5x86, you can set some bits and enable/disable the branch target buffer. This, of course, dramatically affects BogoMips. So, if you do this, you have to fiddle with a running kernel.
Most of the time, you can alter a running kernel, but not always. Both methods are probably necessary.
