> Does booting with radeon.disp_priority=1 help?
For some reason, passing that option at boot seems to disable KMS on my system. I've tried it both without a radeon.modeset declaration, and with radeon.modeset=1, and in both cases Xorg.0.log shows KMS to be disabled when radeon.disp_priority=1 is on.
