Problem is that CPU clockrate isn't architecture independent. Even with the pentium, there is the CPU core speed and the bus speed. With many laptops, the CPU clock rate can change depending on the battery and power (APM/ACPI) settings. Clock speed between even AMD and Intel parts aren't, strictly speaking, comparable, and clock rates between sparc, ppc, and intel are of course just silly. There's always been a tradeoff between synchronous and asynchronouse digital logic, even back in the days of vacuum tube computers, and I heard a rumour that sun is designing an "asynchronous" CPU (which might conceivably mean no clock at all.)

What might be useful is the whole "CPU" line that comes out of the kernel, much like the "kern.version" string that already exists. I'm not sure it's useful for much past labels on automated benchmark results though.
