Well, unless the intercooler had completely fallen apart or been clogged, it's not likely to be a huge factor, but it's worth looking at anyway.
From the sound of it, the boost gauge is working and the turbo is giving you a little bit of pressure (not enough to overcome the vacuum but enough to reduce it a bit). I'm betting it's either a bad wastegate or a leak/obstruction in the intake somewhere. If the car idles fine it may be hard to find as it may only manifest itself when the turbo starts to spin up. If it's not the wastegate and you can't find a leak, you might want to take it to a good Saab dealer or mechanic who could better troubleshoot the system.
Good luck!
