In both cases the verbose output shows that the authentication succeeded okay, but the session itself just seems to die with an "Exit status 255" message (followed by "Connection closed" for sftp).

The Local System account does not have the permissions necessary to permit
pubkey authentication to work on W2K3.  Did you install with ssh-host-config
and ssh-user-config?  ssh-host-config will ask you if you want to create the 
"sshd_server" user that will have the proper permissions to permit pubkey 
authentication.  See 'usr/share/doc/Cygwin/openssh.README' for more details.
