It's kind of strange when Commodore was making x86 boards for Amiga's before PPC ever came along. Amiga's real roots are more x86 than PPC.
That's not really relevant, those are for running typically DOS apps on the amiga without going through emulation, and has nothing to do with being "real roots" of Amiga at all. Same type of cards also existed for Macs and Atari, for example.
IIRC, Commodore engineers were looking at going PA-RISC after m68k, PowerPC at the time did not exist yet.
