2005 XC90 T6 AWD making a whirling noise upon acceleration

An auto parts supplier would know.

Could be a catastrophic failure in the mist, especially if the front side of your driveshaft falls while cruising down the road and then your car pole-vaults itself like an olympian. There are remote audio+video systems that you can install under the car to use as an extra set of eyes and ears to help pinpoint the problem. But, yes--get it looked at quickly.

Antifreeze out of the exhaust would be from bad head gasket.

check your belts

Your car need a few good screws ;-)
