Not sure if you need the structure or the data; ideally you want both of course. I haven't lost data since a sql server 6.5 bad service pack but here is what I did then:

I've had some success rescuing data by using the non-clustered indexes to retrieve it when the clustered index tree is toast. You just need to be smart enough to write the correct WHERE clause and maybe jump over data pages that are bad. Works in a pinch.
