It's wikipedia, so take it for what it's worth, but this list seems to be fairly accurate:
http://en.wikipedia.org/wiki/List_of_NHL_players_who_have_signed_offer_sheets
It lists all the players who have ever signed an RFA offer sheet, and the only goalie listed is Ron Tugnutt, way back in 1996. At the time Tugnutt was coming off a full season in the AHL as a 28 year old, so not at all comparible to Bernier. Good pick up for Ottawa though, as they didn't even have to give up any compensation (contract was so low, it was in the 'no compensation' area) and he went on to play almost four seasons as Ottawa's co-number one.
Back to the point though, odds aren't good that Bernier would get a RFA bid and I'd actually worry more about Voynov getting one than Bernier at this point. That said, this is likely the worst year for potential RFA bids, considering the cap is dropping by $5.9 million and typically the only way you'll get the player you are bidding on is if you overpay to the point the team that has the player doesn't want to match.
