Hi, all! I am curious: if the MacBook is indeed "refreshed" in the coming months (or whenever) with the Santa Rosa chipset plus a CPU "bump", do you reckon it will be able to fully address 4GB of RAM? My understanding is that the current C2D MacBooks can address 3.3GB of RAM if matched 2GB sticks are installed. Am I correct in assuming that the amount of RAM a computer can address is dependent on its chipset? Or is it, instead, dependent on the CPU? Or perhaps both? Thanks!
