I have a very similar card in my Gentoo laptop (Mobility Radeon 9700, I think maybe it's the same as 9600 but clocked higher). I tried KMS radeon driver but had some issues, maybe it was user-error but when I disabled KMS everything went back to normal. Otherwise if you want to stick with KMS all I can think of is to try different AccelMethod settings in your xorg.conf to see if you get better performance from one of them. I think maybe you need to disable console framebuffer as well, in case you're using one.
