Not the following line in the xorg log when I boot with rc6:
(II) [KMS] drm report modesetting isn't supported.
In contrast, with rc7 I get this:
(II) [KMS] Kernel modesetting enabled.
As indicated in the bug report summary, if I add nomodeset and radeon.modeset=0 as a command line option, 3D performance with rc7 is the same as with rc6 (quite acceptable).
