I don't know if anyone has seen this yet but the Irish Registration Indexes are online here http://search.labs.familysearch.org/recordsearch/start.html#p=2;t=searchable;c=1408347 .  The summary of the records listing says there are no images but I was able to see images for some so I don't know if all images are up yet and the collection isn't complete online yet but it's a wonderful start!
