I received the following response from Crucial customer service when inquiring about an 8GB upgrade kit for my Late '08 MacBook unibody 5,1. OWC offers an 8GB Ram upgrade for MacBook/MacBook Pro 5,1.
"Thank you for contacting Crucial with your memory needs. As this time both Apples's testing and Crucial's testing show that the MacBook (13-inch, Aluminum, Late 2008) has a system memory maximum of 4GBs. It you wants to install more than the recommended memory I would recommend going with OWC."
