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.
