As has been mentioned many times before on this board, the issue is address space. Memory helps in performance but you can't get to square one without the address space. I think that I've seen one Pentium 4 notebook that does have more than 2 GB of memory available in my search for high-end notebooks. So it can be done but it doesn't seem popular right now.
A cheaper solution would be to buy a USB device that connects to a RamDisk (I saw a PCI-card that would take all kinds of different cheap memory to construct a RamDisk) and setup your paging file to use this device.
