   From the sources (I have no walnut board) the 405 also traps.
   
   At least 1.6 has a shared/powerpc with X, games and text.
   Therefore the powerpc should use a feature set useable on all cpus.

that's OK;  if someone uses -m603 they are doing that themselves
and it doesn't matter ... i think jason's idea is still useful.
