Hmm, Ok, I've got the new changes and removed all my previous stuff from _config.php. Added a 'Entry' configuration type (with default values for the fields) via the admin area, saved it, but then hit 'reindex' or visit /dev/tasks/SolrReindexTask but still only get 16 Objects indexed (my pages) the 140 something data objects are ignored. Also the search on fields list doesn't appear to have Entry's fields....
I'm using Ubuntu's solr package and don't see any obvious errors in the log but I'm not really sure what to look for in there but here's a sample
