MBP - Noise after firmware update

I dont know if this still works after the update, and its certainly not a solution (since it removes the point of having a dual core laptop) but I would be shocked if apple didnt accept this as proof of the cause of the whine:
On the install discs, on disc one, there are a load of tools (developer tools or something). One of the packages (CHUD package) installs a small tool which gives you processor settings in the menu bar and in system preferences.
Using this you can select 1 or 2 cores. If you select 1 core, the mbp turns near silent (i.e. whine gone) which to me proves undoubtedly that the whine is due to powersaving on the 2nd core.
Whilst this does remove the point of being dual core, it sure as hell saves battery life, and my temperature drops by about 5degreesC according to my temperature widget (it feels a lot cooler too).
Anyway, it could be worth seeing if this still "solves" the whine after the update.

This is ridiculous. Apples needs to fix this now. Getting the noise to go away reminds me of cheat codes for the Nintendo 64, as is Job was saying, "all right, all you have to do to get the whine to go away is enter A, B, A, B, Right, Left, Up, Down, B, A, Start."PatrickF said:

Except there are benchmarks out there showing that turning off one core actually hurts battery life. Since there is now only 1 core instead of 2, it has to run at a higher clock speed than if there were 2 to get the job done...resulting in the same, or worse battery life.
If you open photobooth and then force quit, the noise is goes away. That's what I've found works the best.
Edit: I should note that this works until you use the iSight camera again, but you can always force quit whatever app uses the iSight and keep it silent.

If you're in a quiet situation (like writing an essay or whatever, so you aren't doing many intense tasks and you're probably plugged in power-wise anyways), turn off one core so that the noise shuts off. Yes, the running core will have to run at a higher clock speed, but if you're only typing or whatever, you'll be fine regarding battery life if you're not plugged in.
If you're doing some intense stuff, then use both cores and either turn on some light music or get earplugs.
