You have been subscribed to a public bug: I just freshly installed maverick rc on dell studio 1555. I had tried latest kernel (2.6.36rcx) from mainline on lucid on the same machine and ati open driver had no problem at all with KMS enabled. On maverick, KMS enabled causes very slow performance (30-40 fps on kwin with no window). If i disable kms with radeon.modeset=0 performance gets a lot better, but un-minimizing windows on kde crashes x server. All info refer to kms enabled.
