Ambient Light Sensor too sensitive - brightness changing too frequently

Well my 3 day old MacBook Pro 17" (Mid 2009) 2.8GHz, 4GB RAM, 500GB HD 5400RPM computer's screen brightness is adjusting itself quite frequently - and i believe it is too sensitive.

I found this article, which points to a 2008 MacBook as having the same problems - could this actually be the case for my Mid 2009 MacBook Pro as well?

"MacBook (Late-2008) Screen Brightness Undesirably Varies

Still on the topic of unibody MacBook displays, MacFixIt reports that while the new machines' displays are relatively bright thanks to LED backlighting, dimming the displays a little, as many users are wont to do, highlights some problems, namely that the backlight intensity will then not stabilize but persists in a constant state of flux.

According to MacFixIt, Apple employs an algorithm that brightens the display and dims the keyboard in bright light environments, and vice-versa is in dim-light situations, but in the new MacBooks, the ambient light sensor lives at the top of the screen with the iSight camera and its light sensors may be a little too sensitive to minor fluctuations in the ambient light, resulting in screens changing their brightness frequently.

Hopefully, Apple will address this troubling issue with a software patch."

If anyone else is having this issue, i would like to know if this is a known issue with these new Pro's, thank you.
