How much blown-in cellulose can you put on top of a 5/8" drywall ceiling?

I have trusses on 24 inch centers and plan on at least 12 inches of cellulose. When do you have to use something stronger like OSB and how is it finished?

Larry,
For a detailed discussion of your question, see Is 5/8 drywall sufficient to support R-60 cellulose in a ceiling?
