    So, I did more tests. As I wrote previously, it's normal that radeonfb
    as a module doesn't work when offb is in the kernel, we don't quite have
    an infrastructure to deal with driver "replacement" yet.

    It seems -mm2 definitely has some problems regarding loading of modules,
    it pretty much fails loading all of them for me with some
    kobject_register errors, I haven't really found out what was up, but
    then, I didn't have much time neither.

    radeonfb built-in operations seem to be ok on my PowerBook3,5 (ATI M9
    based), I'll try on a PowerBook5,4 (same as yours) tomorrow hopefully.

    Does the machine hang with the screen completely cleared ? Do you see
    the penguin logo ? Did you try just using pmac_defconfig ?

    Ben.
