I can confirm that I get the software rasterizer on current Precise, running on a PowerBook G4 with a M7 (r100) card. I think this is because the atyfb frambuffer driver is loaded (compiled into the kernel) and it blocks KMS from working, which is needed for the gallium mesa driver. However, when I disable the atyfb driver with the "video=ofonly" boot option and use KMS, the machine easily locks up, or goes nuts switching modes at a rate of around once per second.
