zgirnius:
When Dumbledore learns that Voldemort took some of Harry's blood into 
his body, we are shown that infamous 'gleam of triumph'. 

> GoF:
>"He said my blood would make him stronger than if he'd used someone 
else's," Harry told Dumbledore. "He said the protection my - my 
mother left in me - he'd have it too. And he was right - he could 
touch me without hurting himmself, he touched my face."

>For a fleeting instant, Harry thought he saw a gleam of something 
like triumph in Dumbledore's eyes. But next second. Harry was sure he 
had imagined it, for when Dumbledore had returned to his seat behind 
the desk, he looked as old and weary as Harry had ever seen him.

zgirnius:
What I take this to mean, is that long before the conversation cited 
above ever took place, Dumbledore has known about Harry Horcrux, and 
despite long thought devoted to the problem, has been unable to 
devise a solution to it which does not involve Harry's death. Until 
this moment, when he sees the possibility of the "blood Horcrux" or 
however you want to term that bit explained in DH, that by taking 
Harry's blood, Voldmeort ensured that Lily;s sacrifice lived on in 
the world and Harry could not be killed by Voldemort.

This does not prove he knew right then in PS/SS, he might have 
figured it out in the intervening years, but I would guess he knew no 
later than the start of GoF, when Harry confided that his scar hurt 
to Sirius (who passed that information on).

Though I would not rule out his knowing right from the very start. It 
would be a reason to maintain a distance from Harry, emotionally. 
Because if he cared for Harry, he would dread one day have to tell 
the boy that to defeat Voldemort, he had to die himself.
