yes, in general; overheating and white smoke is a good indication for a
blown head gasket, or worse, a cracked head.

not for long

Could be the head gasket but it could also be the turbo.
My 9-5 started blowing white smoke and it was the turbo - replaced
under warranty, fortunately: perhaps a bit late for warranty for the
9000....

Go to a mechanic and have a leakdown test performed, that'll tell you where
the problem is. 95% chance the head gasket is blown.
