The MacBook Pro and its CPU

Increw is working on Speedit, the extension that allows the monitoring of the Core Duo. Doing so, he found some useful stuff:
- To start with, the removal of the battery from a MacBook Pro blocks the CPU's clock at 1GHz. No way to go beyond. While this is obviously not a step aimed at increasing the autonomy, there is still no clue as to why it has been implemented.
- Some Core Duo seem to be bugged in such a way that the thermal diods won't work. While this is not a real handicap when working, it can have serious conequences such as preventing emergency shutdown in case of overheating. Intel has proposed an update. Apple should do so as well.
- The latest SMC update had the folowing consequences: a higher rotation speed for the fans; the CPU's temperature down from 5 to 10C; the voltage of the CPU was modified; and the cooling system's temperature threshold was lowered, with cooler but noisier machines as a consequence.
We would definitely welcome more information from Apple about these updates and what they do, instead of using them blindly as we do now.
