I am also seeing a drift in the n_live_tup value compared to actual row count on the table on PG9.0.6
It drifts after a vacuum , you can bring it back closer to the actual number by running ANALYSE several times, you can lock it back into the right value with a vacuum full, but then if you run a vacuum it shows a n_live_tup less than the actual rows in the table. This is on a table seeing 80% HOT updates. Its a table that is heavily updated.
