You might want to consider the web browser Slimjet at www.slimjet.com.  Looking at the specs of your laptop, it seems like you can increase the RAM to 1GB.  That might help, too.

Another alternative would be to see how things work with the Chromium browser.  That can be installed via Lite Software / Install Additional Software.  This and Slimjet can give you a Google Chrome-like experience.
