I am replacing an old (1991) ceiling fan which is currently connected to three-way switches. There are two 2-wire cables coming to the existing electrical box. Both of the blacks are hot, that is, it seems like both cables ran power to the fan (I had to flip two separate breakers to cut power to the fan). The old fan had all the whites wired together, one 2-wire black to the black on the fan, and one 2-wire black to a _blue_ wire on the fan. The replacement fan just has the standard black, white and ground. All the wiring diagrams I can find only have one power source coming to the electrical box, and would wire the 2-wire blacks together, the fan's white to one 2-wire white, and the other 2-wire white marked black to the fan's black. What is the correct way to wire this?

From what you've said, I believe the black-to-blue connection was the lighting feed to your old fan, and the black-to-black connection was the fan motor power. That would, to me, explain the need to trip two breakers to kill the circuit.
If the new fan has lights, rewire it exactly as the old fan. If there are NO lights on the new unit, just cap off the "extra" hot wire with a wire nut. If you do have lights, connect the blue wire as before.

I agree with Hank, it sounds like you don't have it on a 3 way, But 2 separate switches in 2 Locations that are single pole switches, one that controlled the light and one for the fan, and your new fan has Just a black/white/ground, hook it up to the switch that would be most convenient for you, as for the other switch will no longer be used
