Okay, well it looks like it's a problem with DSA alright.  RSA works on 
the same host relationship but the old DSA didn't.  I made a new DSA 
key-pair and that works too.  I'll have to go read up on when or if DSA 
is even recommended at all anymore.  At any rate, they do allow new ones 
to work.  Funny how I never got the security update on CentOS.  I guess 
that's a feature of their "enterprise" quality system.

Thanks you guys for the quick and helpful response.
