Ah, so stupid of me ... I totally forgot to put my main point about 
Dumbledore's lack of surprise (knowledge) in my previous post.

To continue from where I left:

OOTP, p 737 uk edition.

Dumbledore: "But she (Petunia) took you", Dumbledore cut across 
him. "She may have taken you grudgingly, furiously, unwillingly, 
bitterly, yet still she took you, and in doing so, she sealed the 
charm I placed upon you. Your mother's sacrifice made the bond of 
blood the strongest shield I could give you."

Ok - so how DID Dumbledore know anything about Lily's sacrifice at 
that time? Harry was a little more than a year old and the only 
person to tell what had happened at his home that night. Not a chance.
Alas! Someone else must have been in the house to witness what 
happened and told Dumbledore that Lily actually gave her life for 
Harry. Who? 
And so, Dumbledore must have lied to Minerva when he told her that he 
didn't know how Harry had survived the attack.
