I haven't looked at all the new clock/timer code, is there any  
utility in having support for more than one clock source?

There is if the main clocksource has some issues where it can't be used.

    You mean, having more than one clocksource is *useful* in this case?

Yes.

    Well, the decrementer frequency may change, at least in theory (if the bus 
clock changes).

Does that happen very often?
