I also had the squeal and my dealer replaced my belt and all pulleys to try to curtail it. 2 months later, I am still getting the squeal on cold startup (30 degrees or below pretty much). My dealer said he'll adjust the tension next time I'm in for service as the new belt may have stretched.

Anyway, if this is in fact a normal cost of cold weather, then I got a free belt and pulleys for nothing! That's exciting, as I think I would have replaced them at my 60k service (17k miles from now) anyway! And that would have NOT been warrantied.

Take this for what it's worth but if I remember correctly when the boxster starts up in the colder weather the air pump kicks in to reduce the start up emissions, and that noise is pump running for the first 15-30 sec after a cold start. However your description of the squeal sounds like it might something else.
