Our 2001 Olds Intrigue, experiences a vibration when applying the brakes at 65+ that doesn't happen at slower speeds. I checked the pads and rotors and they seem to be in fine shape. It doesn't cause the car to veer or anything, but is very unsettling.

It's your anti-lock brakes in combination with your rotors. My 1999 Cavalier did the same thing until I got my rotors turned. Your rotors are warped...

Brake Vibration At High Speeds

If a vehicle has a pedal pulsation, measuring rotor thickness at six to eight points around the rotor should reveal the variation that's causing the problem. It doesn't take much, only about .0003-inch on some vehicles, to cause a noticeable pulsation.
The Fix: Take or car to a shop that can check it all out and to make sure that there is no other problems with your brakes and to make sure that your rotors have not gotten to then to resurface. Have them resurface rotors on the car if they can. That makes sure you not getting any stack run out from your hubs and rotors.
Cheap Fix: Take off your rotors and take them to a parts place (Autozone, Napa, ect...) that can resurface your rotors. Just have them make sure that the rotors have not gotten to thin.

could be several things. a tire out of balance, a broke belt in a tire, you may need a brake job and have the rotors turned. my pontiac firebird was doing the same thing. i got new brakes all the way around and had them to turn the rotors and it fixed mine. my mechanic told me that any these things could be causing it. since i had just recently bought a new set of tires i tried the brake job first. apparently he was right.

If you can feel it in the brake pedal, it is probably the anti-lock brake system modulating the pedal pressure. It could also be a warped rotor, but you could feel and hear that at any speed when braking.

My 62 Impala just had front disc brakes installed. At speeds under 40, all is fine. At speeds above 40, especially at freeway (65mph), front end shakes significantly. What's going on?

If your rotors and suspension are okay then I would definitely try to replace the pads themselves. I do agree with your pads being uneven but it could also be the pistons in the calipers that may not be too great regardless of the low mileage. Although the rotors are not warped consider getting them turned; also doing a tire rotation could help.

Quite possibly one of your rotors is warped and that will cause what you describe. This condition cannot be easily seen while doing just a visual inspection. This is a fairly common problem.

Warped rotors - if they are still thick enough, Autozone can machine them - if they are not, then you will have to replace them.
If you need to replace them, have the new one's machined (trued) since there is no such thing as a new rotor that is true.

IT IS THE ROTORS,U CAN CHECK RUNOUT BY EYE.IT HAS TO BE DONE WITH A DIAL INDICATOR,THE ROTORS WILL LOOK FINE BUT STILL MAY BE WARPED.
