    Just to be really really sure, I repeated the tests. I even checked
    that the image/label combination in /etc/lilo.conf was what I intended,
    but the uname -r should show what's what.

    Same results, -mm2 broken, and -mm1 reads the disk. I even tried
    other CD's just to make sure I didn't have something weird. Same results.
