Import a SharePoint 2007 list to 2010

SharePoint 2007 and 2010 both support .stp templates. So the east way to migrate a list should be to create a template in 2007, upload to 2010, and create the list from it. Except that wont work, SharePoint 2010 complains that the it doesn't support version 3 templates. Fortunately there is a fairly easy way to fix this.
