It's hard to tell, but if it's new and different, I'd be inclined to make an appointment at the Genius Bar of your local Apple Store. They'll check it out for you.

I've had this problem for a while too. I have one of the first Unibody 13" Macbooks and when my battery is getting low, or sometimes even when plugged in the bottom left of my MacBook starts to squeal. Whilst I have no real solution to the problem I have found one thing that works instantly.
I have a system preference tool called BetterTouchTool installed on my MacBook that lets you assign pretty much any multitouch action you can think of to any event you want to occur. I have 5 finger tap set to send my display to sleep. As soon as the screaming starts, I 5 finger tap and the noise stops immediately. I then just wiggle the pointer and I'm away again, no screaming in earshot. Strange I know, but it works every time for me.Macbook Unibody, Mac OS X (10.5.5)
