Welcome to the Apple Support Communities!
We understand that you are not able to get 2560 x 1600 resolution on your Apple Cinema Display which is connected via Mini DisplayPort to your 2009 MacBook Pro.
According to the following article, this can happen if the display has a single-link DVI connection instead of a dual-link DVI connection. You did say in your question that none of the hardware has changed, so we would suggest troubleshooting the cable itself. Do you have a separate dual-link DVI adapter to test with?
Apple Cinema Display (30-inch DVI) might show 1280 x 800 as maximum resolution - Apple Support
Cheers!
