Re: Dice odds without dice
It's statistically poor unless you reshuffle after each card pull, which is a hassle (the odds of rolling three on 3d6 is 1/216. The odds of pulling three aces from a deck of 24 cards is 1/552).

Re: Dice odds without dice
Keep separate piles. Or keep one pile and draw until you have cards from a number of suits equal to the number of dice - two suits foe 2d, three suits for 3d, four suits for 4d, using only the first card drawn from each suit for your "roll."

Also, if you need more cards (for ease of shuffling, smoother statistical spread, etc) just ditch the Ace from each suit and the two Jokers. Assign the King 13, Queen as 12, the Jack as 11, and then divide by two, round down. Viola, 1-6 distribution (but with more maths). Basically I mention this method (deck of cards) since I always have a deck of cards on me* when going on a trip, and more importantly, many 'rest stop' style gas stations sell decks of cards, but not often dice. * I also always have dice, but that's less relevant at the moment.

Re: Dice odds without dice
I was going to suggest putting numbers on slips of paper and drawing from a cup, but cards are far more elegant (and they're pretty cheap.)

Re: Dice odds without dice
I've been in this situation before and thought about how I would handle it. My solution was to use the english language as my source of randomness.
I explain it here, including links to the tables. Ironically, I haven't had a chance to use it: I've either had electronics or dice with me ever since.
