Spark,
I don't think it's quite as simple as you make it out to be. Do you really think that Motorola would let Apple sell chips rated for 1.0 ghz as "overclocked" 1.25ghz chips? Of course not. It's a lawsuit waiting to happen. Plus, Apple wouldn't do something that stupid.
The 1.25ghz G4 are rated at 1.25ghz, therefore they are 1.25ghz chips. Not overclocked 1ghz chips. Period.
I think the issue lies with Apple. Why can't they put in a 167mhz bus into the TiBook? Seems like an easy enough task.
In my opinion, Apple is purposely crippling the TiBook so that the PowerMac looks better on paper. Apple has a history of doing this. Look at the original white iBooks. They have 66mhz busses in them even though 100mhz busses would have worked just fine. It would not have added to the cost of the machine, but Apple didn't want the specs of the iBook to be too good, or many consumers would have opted for an iBook over a TiBook.
Anyways, I'm sorry that I took the thread off topic.
