Minimum recommendation for vista about RAM is 1GB. Regardless of your lap top model your memory is insufficient for using vista. The best option is buying 2 pairs of 1gb and install it to your lap top if your main board supports (I think it will support it).
On the other hand for new computers and lap tops its hard to find driver for XP but for older ones its better to continue working with XP. I am sure you wont be able to get the benefits of vista without Core2, Core2 Duo, Core4 Duo processors.
