Very possible to get around.  Make sure the private key for root on the 
remote machine is available to the system user on the local machine and 
then specify that file with the -i option to the ssh command.  What is 
almost certainly happening is that your ssh command defaults to the 
private key for system user which is not the same key as your root (your 
e-mail isn't 100% clear to me as to whether you are using the same key 
for the system user and root, but it appears you aren't).

If you're going to do that a lot, you can set a default in 
~systemuser/.ssh/config to specify that all connections to root at remote 
should default to using root's private key.
