It may be true that most of the people that *you know* are capable of producing drivers for PCI cards have an Iyonix and they might not buy an Omega in addition to it. But you can't assume that you know all the people who are capable of producing drivers. So your hint that there might be a shortage of authors for Omega-PCI drivers is spreading FUD.
@Steve: I am of the opinion that it was not such a smart move to use the Linux PCI code as a base for the ROS PCI layer. I think the FreeBSD code would have been a much better choice.
