Some interesting quotes from the Council of Elrond.
Toward the beginning of the Council, after the tale of the ring by Elrond and the interjections first by Boromir and then Aragorn:
"'Then it belongs to you, and not me at all!' cried Frodo in amazement, springing to his feet, as if he expected the Ring to be demanded at once.
'It does not belong to either of us,' said Aragorn; 'but it has been ordained that you should hold it for a while.'
'Bring out the Ring, Frodo!' said Gandalf solemnly. "The time has come. Hold it up, and then Boromir will understand the remainder of his riddle.'
There was a hush, and all turned their eyes on Frodo. He was shaken by a sudden shame and fear; and he felt a great reluctance to reveal the Ring, and a loathing of it's touch."
And then near the very end right before Frodo speaks up saying he will take the ring are these words:
"A great dread fell on him {Frodo}, as if he was awaiting the pronouncement of some doom that he had long foreseen and vainly hoped might after all never be spoken."
And then after Frodo speaks, Elrond talks of "this task having been appointed to [Frodo]".
Thus I think that while the Ring had already had an effect on Frodo and was attempting to use Frodo (or any of its bearers previous) to get back to its master (as Bilbo himself jumped at the chance to carry the Ring before Frodo, and Gollum himself ever sought the ring after Bilbo stole it), that the interpretation of the ring poisoning Frodo remains a possibility. I think however that the true driver for Frodo taking the ring was rather that a Higher Fate, (which is spoken of as having brought the Council together in the first place), was 'ordaining' that the ring should be carried to Mount Doom and destroyed by Frodo, in spite of the 'despair or folly' apparent in such a task. Thus, in my reading of that chapter, Tolkien envisioned that Fate or some higher power was overruling/overpowering any draw the Ring had on Frodo and driving him to accept the task of taking the ring to Mordor.
I'll have to go watch that scene again though to see whether this interpretation is captured at all in the movie.
