'Pennies': You will not be able to sell any 'dividend' stock until it is 'settled' in your brokerage account. It is different when your broker has purchased stock for you - you can sell it immediately via the same broker.
When you are in a position to sell your dividend shares, the price will already have been adjusted to reflect the split. Which, at present means you won't be able to sell them as there will be no takers at .0001 and you can't put a sell order in for less.
But for your 'entitlement' to dividends, then follow the postings of the written brokerage advice from Ameritrade (someone posted) or the SEC I posted which details the same.
