The Apple Store just replaced the entire display of my early 2009 MacBook Pro for free, and it's been out of warranty for nearly a year. I was also having the problem of the aluminum housing separating from the glass, but all the way along the bottom and partly up the sides.
I actually took a photo of professorpolymath's post above to bring with me, and it served me well - I was able to give the tech assisting me the referenced article, EM209, and he pulled it up right away. I was out of the store in 15 minutes, and got the call that my repair was complete (completely free) less than 24 hours later.
