Why the limit on RAM?

[alex.purple.mac]

This is pretty much what the title states... I have the first generation macbook with the intel processor, and I was wondering why there is a limit on the amount of RAM I can put in? I have maxed it out to 2gb at the moment, and whilst I don't desperately need 4gb, i would be nice to have a faster macbook if I wanted one.

The memory controller can't handle more than 2x1GB

Why is that? And is it possible Apple can change that due to software, or is it a physical limit?
