The AmigaOS was designed for a big-endian byte order. PPC is either big or little endian EXCEPT for the PPC 970 series which is strictly big-endian. Intels and AMDs are all strictly little-endian with a BSWAP opcode to reverse the endian if necessary.
If you want to run Amiga software on an Intel PC without losing a lot of performance (running BSWAPs all of the time) then your only option is AROS. AROS needs all of its software to be recompiled from AOS 3.1 compatible sources and even then there isn't much available for it.
As for the PPC being a lost cause, it wasn't when Phase 5 started making the PPC accelerators for the A1200/4000 and it isn't now. The Cell processor will be commercially available soon and there is promise of open archetecture computers being made from it. Best of all the internal archetecture is so different from anything else before it (except a RAM-expanded C64 :-) ) that only a flexible Amiga programmer will be able to support it well. We'll see how it goes.
