33 I have a very similar card in my Gentoo laptop (Mobility Radeon 9700,
34 I think maybe it's the same as 9600 but clocked higher). I tried KMS
35 radeon driver but had some issues, maybe it was user-error but when I
36 disabled KMS everything went back to normal.
37
38 Otherwise if you want to stick with KMS all I can think of is to try
39 different AccelMethod settings in your xorg.conf to see if you get
40 better performance from one of them. I think maybe you need to disable
41 console framebuffer as well, in case you're using one.
