You might want to hold off on that 512 stick - I don't think the clamshell iBook can accept an sodimm that size. I think the maximum size for that line is 256Mb. Check with an online retailer first to see if that 512 will work. I think the first iBook to take that size was the first of the white new shape iBooks, the 500Mhz one.
