    Unfortunately support for PowerMac framebuffers has become less and less
    reliable after about 2.4.22. But newer kernels are only needed if you
    want to have newer features like XFS support.

    I think there is a PowerMac ppc kernel on the debian site from the 2.4.x
    age that might work better for you.

    Are you using the built-in framebuffer of the 7300 or a PCI graphics
