Before this, it said:

*** WARNING: identical binaries are copied, not linked:
        /usr/lib/debug/lib/modules/2.6.24-9.fc9/vmlinux
   and  /boot/vmlinuz-2.6.24-9.fc9

In find-debuginfo.sh the two files are compared with both
'cmp' and 'eu-elfcmp' -- something has changed that causes
them to be considered different where they weren't before.
