Ram Upgrade Qs - Atom n270

I got a netbook and I'm planning to upgrade the ram from 1 gig to 2.
The netbook has atom n270 on it and the FSB for the processor is 533.

If i understand correctly, a ram with higher FSB, will auto-downclock to match the CPU's FSB.

So is there any point of buying a DDR 2 - 800 (PC 6400) ram for atom N270? Should I just buy PC4200 (DDR 2 - 533) with lowest CAS number, because it matches the cpu's fsb?

My laptop manufacturer suggests using PC 5300 or PC6400 in the manual though... I don't know why that is.

Also, the 2gb limit for netbooks.. is there a way to bypass it? Has anyone tried using a 4gb stick with their netbooks?
