Thanks to Keith who pointed out that "klogd conversion of addresses to
symbols is a pile of crud."  Here's what I'm getting out of ksymoops
now.  It's not as much, since it's just the parts I copied down by
hand...  (I'll get it next time.  Whenever that happens to be.
Installing the ksymoops package didn't trigger it.)
