I see the performance regression with the rv280 (Radeon 9200 PRO) graphics card. Disabling KMS does work around the problem, with the odd drawback that the text on drop-down menus for the non-QT apps I use in KDE (i.e., File/Edit/View in Firefox or Buddies, Accounts, Tools in pidgin, for example) do not render properly, making the apps hard to use. With KMS enabled at boot, I do not have any boot display problems other than the performance regression. Disabling compiz without also disabling Kernel Mode Setting does not work around the 2D aspects of the performance problem for me.
