Exactly. If I don't want to do this anymore for some users, this is up to me. The alternative would be stopping Poseidon development completely, but this is not so favored by most users.

It's not "lacking" those. Poseidon was developed using E3B USB boards and the E3B card drivers were paid for. As I don't have a PCI capable Amiga, I cannot develop the PCI drivers myself.
There are third party PCI drivers such as the ArakAttack package for Amithlon, Prometheus and theoretically OpenPCI, which has turned out be working on Mediator too, recently. It was bundled with Poseidon and sold through IOSpirit some years ago but is now freely available. There are the MorphOS PCI drivers for uhci (Frank Mariak), ohci and ehci (Nico).
