The PowerPC kernel is currently setup with KMS enabled, BUT the legacy framebuffer radeonfb is still built in. Although this is obviously not an ideal setup it seemed to work okay as a default setup up until August when UMS was dropped in quantal. I'll attach a log from my 12.04 install so you can see what used to happen. Despite the message "[KMS] drm report modesetting isn't supported" the radeon driver continues to load in 12.04 although drm/dri is non-functioning (because of the presence of radeonfb). Now in quantal the radeon driver unloads pretty much immediatly after the "[KMS] drm report modesetting isn't supported" message. The fbdev driver takes over in 8 bit pseudo colour which causes all sorts of problems (bug 1046951). Is it possible to have KMS without drm? DRM still causes a lot of freezing problems with radeon KMS on PowerPC and this is one of the reasons radeonfb is still included in 12.04. Radeonfb is also needed for suspend. Is there a way to have radeonfb and KMS working together (without drm) which seemed to be the case in 12.04? If not then radeonfb should (IMHO) be removed from being built into the PowerPC kernel, but I currently would hit a new bug with that (bug 1058641).
