What about running OS4 on a PPC A1200/4000? Even though the option to add an A1200 motherboard to the AmigaOne may be gone, I presumed it would still be possible for OS4 for access the chipset if running on an AGA machine - or has OS4 for these machines been dropped?
I don't know if the original poster was asking only about OS4 on AmigaOne, or meant "AmigaOne or OS4".. I just thought I'd ask anyway.
