Sorry, I don't think anyone here has had that problem...especially on a 4th gen.
You might want to check out an interior specialist...sort of like a body shop, but they only deal with interior issues.
When the Olds dealer damaged my lower dash (while taking out the center console) in my Alero...they call one of those guys 'in a van' that can to the dealership to repair it...basically the rubber/vinyl was cut/torn...they used a combination of chemicals and heat. Honestly, you could hardly tell it was repaired.
But seems like your problem is over the passenger side air bag...not sure anyone will 'touch' it...
