The turbo oil drain seal will leak regardless of driving style and is fairly easy to fix.
The intercooler weep hole will leak more when the turbo is at full boost, 3/4 or more throttle. Remember, the weep hole drips condensed oil only while the car is being driven, not at idle. I managed to "cure" the drop of oil on the garage floor by drilling a 1 inch hole in the air guide directly below the weep hole, allowing the oil to drip on the highway and not collect on the air guide to drip later.
If you google volvo turbo repair you will find this fun video:

Unfortunately, I lost/forgot the link to a great pictorial showing step by step turbo seal repair. I think it was a UK site.
