Core Duo: battery lifespan and USB2

Couple of days ago, we were reporting a bug affecting the USB2 port of Core duo-based computers; that could affect significantly battery lifespan of such machines.
TG Daily is providing new details and information about this issue; even in sleep mode, the USB2 port would reduce battery lifespan by 25%.
According to Intel, this problem is linked to a bug in Energy saver drivers developed by MS since Windows XP, and the issue is known since July 2005. But Microsoft did not solve the problem yet.
So, in this case, this USB2 problem should not affect Core Duo-based computers running MacOSX.
However, recent comments from Greg Myers, the Core Duo "product marketing manager" , make us thinking that the reality is not as clear as claims by some parts. Due to the poor reactivity on Microsoft side, Intel is working on a firmware update that could solve the issue; but it is not sure that such solution can really fix the bug.
Nothing is really clear. If we consider Apple's "no comments", regarding the MacBook Pro battery Lifespan, on could consider that the bug is more related to a hardware problem than a real software problem. In this case, Apple Notebook might be more affected by this bug than PC notebooks; indeed the MacBookPro is using USB2 ports internally for both the iSight and the trackpad.
To conclude, and according to reliable sources (no really a rumor, a non-official information), the current battery lifespan of the MacBook Pro prototype would be around 3 hours. Apple is currently working hard to gain an additional time frame of 30 to 60 minutes.
