As it seems the MorphOS 1.4.5 PowerUP Edition does not include the latest release of Poseidon. However as Chris Hodges informs on amiga-news.de it is no problem to get it from his homepage (title llink).

According to him there are also MorphOS native drivers for these E3B hardware products available: Highway, Subway and Algor. If you are interested in getting the drivers please contact Chris by email.
