I think you have the best driver you're going to find. The latest driver from Dell is dated 10/30/2007 and it is Catalyst 8.31.
Does anyone know which is really the newest driver for this laptop? I tried the current legacy driver (10.2), and it said that no device it could do was present. Even though ATI radeon xpress series is listed.
It's the xpress 1150 one.
So I just googled for and installed version 9.3 which did install, but I'm left wondering if maybe there's something newer I could be using.
Microsoft update may have a newer driver (so I've been told).
