OK? Leave the exotic HW guys alone or suggest them a better processor option, so they can achieve binary compatibility.
MPC8610. An e600 (aka G4) based SoC, a bit old but pretty suited for Amiga/MorphOS things. e600 comes with Altivec. The 8610 has a fast bus, resonable heat dissipation, most things on chip, is not too expensive (the lower clocked versions at least).
