Hyperion was foolish to make it one board specific.
I dont think that decision was made by Hyperion. I believe it is AmigaINC that has stopped OS4 from running on various hardware by demanding people to pay huge amounts for a license. I believe several board manufactor has asked for a license, but they either got zero response from Amiga inc or they werent willing to go with the terms.
Amiga has stated many times that they are not a hardware company. The PPC decision was made by Hyperion. I don't know about the chipset-specific decision, though it makes sense given the resources required to support multiple chipsets, and Eyetech was the only company to step up and provide hardware.
It's pretty obvious that Amiga Inc. doesn't really care what happens to AmigaOS. I'm under the impression that Hyperion is calling most of the shots, now, when it comes to the platforms supported by AmigaOS. They have to do most of the work, after all.
