Arg,

The include ksymoops, segfaults.

[root@nut scripts]# ./ksymoops ../System.map < /home/bleh/kernoops
Segmentation fault
[root@nut scripts]#

However after reading a recent thread on ksymoops, one of the letters
included an alternate ksymoops availble @
<ftp://ftp.ocs.com.au/pub/ksymoops.tar.gz>.

That produced the following output:
