Hmmm, the Server Guide recommends 644 permissions:
https://help.ubuntu.com/8.04/serverguide/C/openssh-server.html

Though I don't know why this would make a difference in this case, I
assume the program for which you need the key auth is run with the
credentials of oar at lion anyway.

Did you set "PubkeyAuthentication yes" in /etc/ssh/sshd_config?

Did you restart sshd after making changes in /etc/ssh/sshd_config? To
restart, issue "sudo /etc/init.d/ssh restart" on the command line.
