First off, that's a 7 year old computer, not a 10 year old computer. I myself am pretty happy using my 1.25 ghz G4 powerbook with 2 gb RAM that was pretty OK running with 1.25 gb previously. The powerbook isn't all that different than the iLamp. Given their minimal needs, I would do a very minimal upgrade of that computer and just buy a single 512 chip which will set you back $34 + shipping from our sponsor, OWC. That would probably give you a nice speed boost. I wouldn't spend the extra money to go with two 512 chips.
That said, there's a big issue with that computer. If you look here http://www.lowendmac.com/imacs/15in-imac...0-mhz.html , you'll see that there are two diffent types of RAM in that machine, and only one is "user accessible". Since one of the installed chips is a 128 mb chip, I'm guessing that it is the non-user accessible one. It can probably be replaced but you need to find out first which RAM chip you need to replace before undertaking this.
