FYI-- the IRS is rejecting eFilings for the 8910 if the year specified on line 1 is earlier than 2009. I just spent a LONG time on the phone with the IRS and the conclusion we came to is you should put in the "year" of your conversion. They certainly were not confident in this and believe that if you paper file this will not be a problem-- basically it sounds like there is a problem with the electronic rules they have setup.
