There's been some discussion on this in the #mtgox IRC channel.

Things are moving but there's a backlog.

Apparently you can get the data from this URL if it hasn't been sent within 2 hours : https://data.mtgox.com/api/0/bitcoin_tx.php

And then rebroadcast/push the transaction using this URL : http://blockchain.info/pushtx

Mine hasn't showed up in the API link yet so I can't test it.

Some users said it's working ok after a multiple hour delay.
