Dude I so have that laying around! The Brand is Hynix, PC3200 (400MHz) if I'm not mistaken. It's 2x512MB. Came with a Gateway my friend gave me. I need to test it still because I haven't really used it. I can go to a friends house maybe today or tomorrow for it. My dad just created a Paypal so I think you could pay him. You would have to pay for shipping. PM me an offer and details.
edit: I'll try to get it tested asap, it should be working, if not I'll just PM you saying that it's not.
