For now, I accomplished this by hacking up the library and setting the $items parameter in insert() and _insert() to be passed by reference, and then setting
$items['rowid'] = $rowid;
...right before return of _insert()
This way, I get the rowid back in the same array that I passed to insert()
Please let me know if there are any negative implication to this approach, though it seems to be working good at first glance.
