Subject: How do I clear the append-only flag on symlinks?

By means that are best not admitted to, I managed to mark a large
chunk of my filesystem append-only, including symlinks.  I cleared the
flag from all the normal files and directories, but chattr and lsattr
don't want to operate on symlinks.  They say things like:

$ sudo lsattr /boot/vmlinuz
lsattr: Operation not supported While reading flags on /boot/vmlinuz

and I can't delete them, because

$ sudo rm /boot/vmlinuz
rm: cannot remove `/boot/vmlinuz': Operation not permitted

Any ideas on how to clear the append-only flags?  debug2fs is a little
scary, and hacking e2fsprogs to allow operation on symlinks seems to
affect symlink targets and not the symlinks themselves.
