Clocks broken on Mac mini

[Hal Murray]

I poked around enough in Open Firmware to "fix" the clock parameters.  But it 
made things worse rather than better.  I assume some step in my thinking is 
backwards.

I think the most important thing is if they have seen this before, understand 
it, and such.  Have they tested with a Mac mini?

The next step would be a quick summary of what the hardware does and how 
clocking works, and/or pointers to the appropriate documentation. 
arch/powerpc/kernel/time.c reads clock-frequency and timebase-frequency  from 
the openfirmware stuff.  Why both of them?

Does a 1.42 GHz Mac mini really run at 1.42?  Why does Open Firmware say 
1.416666?

Does a Mac mini FM the system clock to get pass the EMI rules?
