NVidia says 8GB, Apple says 4Gb...how much RAM can you put into the new unibody MacBook and MacBook Pros?  Longtime 9to5Mac sponsor RAMJET has found the sweet spot offering up 6GB kits.

MacBook Aluminum:
The MacBook Aluminum uses a new high speed form of memory called DDR3-1066. The system maximum is 6Gigs with the installation of one 2Gig and one 4Gig SO-DIMM.

Non-Stacked IC's: Ramjet uses a Non-stacked module for the 2GB and 4Gig module for the MacBook. The cheaper stacked IC variety of 2GB and 4GB SO-DIMM runs hotter and draws more power, which hurts performance and decreases battery life. Ramjet ONLY uses premium non-stacked chips.

That being said, the 4GB modules currently run at $600 a pop so this isn't for the faint of wallet.  If that doesn't scare you, why not upgrade that hard drive to 500GB while you are at it?

"...why not upgrade that hard drive to 500GB..."

Actually, I prefer going to a 7200 rpm drive. Granted that may limit me to 200 or 300GB, for now ;-)

So is there a screenshot that shows the Mac recognizing and using all 6 gigs?

Isn't it inadvisable to install mismatched pairs of RAM in computers that have integrated graphics cards? I have heard that it can lead to a degradation in graphics performance... Anyone know how this 6GB configuration affects this?
