    I'll be gone for most of this weekend, although I may have time to pop in here and there on my laptop from the hotel from time to time. If nobody has the answer by Monday, I'll post the solution - but hopefully you guys can get it by then.

    OvRide sent me the answer in a PM, and he was correct.

    And Judgement is right. That is indeed a primary clue as to the solution.

    Okay, here is the answer, for those of you still wondering.

    In order to get an equal number of cards in both piles, you count off the first thirteen cards from the deck, then flip them over and place them next to the remaining cards.

    Any cards taken from the first pile would be righted. Say you took thirteen cards and four were face up. That leaves nine face-up cards in the remaining deck. Once you flip the thirteen cards, nine will be face up and the original four would be face down. This works with any number of face-up or face-down cards.
