It found them on the running cluster at /home/sgeadmin/.ssh/id_rsa. Do
you have a volume attached to /home by chance? If so then those are the
keys from a previous run. If not are you using a new AMI you just created?

What happens if you do:
$ starcluster sshmaster thecluster
and then su to sgeadmin:
$ su - sgeadmin
$ ssh node001
Does this work? Also, you should check your debug file in
/tmp/starcluster-debug.log (on your local machine) for any failures
related to ssh keys.
