(1) Everything works okay with the radeonkms driver except that I often get an X server hang shortly after boot. It only happens once. After the first hang, it never happens again. (Until after the next boot). The X server hang involves an unresponsive GPU, and having to reset the GPU. (2) Since applying Greg's suggested "hw.syscons.disable=1", I have had no X server crashes at all. Again. I don't know the significance of this. But I'm happy to help with any debugging that I can.
