Do you know if the module is definitely done once the airbags have been deployed ? I bought my car wrecked, fixed it, replaced the airbags and went to have the car inspected to put it back on the road when I learned that a stupid law here asks for invoices of stuff that MUST be replaced (like seatbelts and airbag module) upon impact. I had to bend over and buy a new module from Ford even though everything was already working fine (no airbag light or anything).
I'd definitely be willing to sell it if you're interested.
