--- Comment #18 from Richard Scheffenegger <rscheff@freebsd.org> ---
For completeness, the awk script with proper indexing:

cat output | awk '
//{
        fr=int($5/1448); 
        if ((fr*1448 == $5) && (fr > 0)) {
                print $1" "$2" "$3" "$4" "$5" "fr; 
                gsub("[^0-9a-fA-F]", "", $6);
                for (i=0;i<fr;i++) { 
                        s = 0;
                        for (n=0;n<(1448/4);n++) { 
                                idx = (i*1448 + n*4)*2 + 1;
                                v = sprintf("%d ", "0x" substr($6,idx,8));
                                s = s + v;
                        }
                        f[s]++;
                        if (f[s] > 1) { printf("#") };
                        printf("0x%08x\t", s);
                }
        }
        printf("\n");
}
