The Amithlon story is a pretty sad one. I might have some facts wrong, because I was never particularily interested in Amithlon, but basically I think it happened like this:
Bernd Meyer started creating an emulator for AmigaOS3.x that ran on top of a minimal linux kernel, which to the end-user would appear like you were running 68K AmigaOS directly on an x86 to all intents and purposes. The system allowed you to run both 68k and x86 native code, and has x86 native drivers for some gfx and sound cards.
As I understand it, he teamed up with Harald Frank who contributed some code to the project. It was sold commercially by Haage & Partner. At this point Bernd was under the impression that H&P had licensed AmigaOS from Amiga, Inc. and everything was hunky dorey.
It turned out that Amiga, Inc. didn't agree and tried to force H&P to stop selling the product. H&P didn't agree, and Harald also thought everything was legit. Bernd didn't want to sell an unlicensed product and it caused a big falling out and the product eventually was cancelled.
There have been continued updates from other people, but mostly the Amithlon project is seen to be dead by most people in Amigaland.
The story is no doubt more complex than this, and I'd suggest a google search for amithlon.
