Well, there is AROS, get coding if you want to see it happen.
But I dont see the point anyway if you just want to run the thoroughly mediocre software you listed. Apart from having the same guts as a x86 PC, now you`d be using the same software aswell? Whats the point..
IMHO the only chance to push an AmigaOS would be to make it run on PS3 or other popular consoles. Too bad none of them are (fully) open for or interested in an embedded full fledged OS.
