*hurm* Well if it is the case that some dev at freescale has assumed
that producing binaries in a certain way that makes sense for the
coldfire series ( which might resemble the original enough to make it
seem sensible )  might explain the slowdown were seeing _across the
line_ ( be it amigaos linux or fuckos).

Bernd Roesch ( now included weather he likes it or not, sorry :) has
also made remarks and comparisons about this. As has the amigaos dev's
of ffmpeg, which has made it bleeding clear in the posts linked to
before

http://www.amiga.org/forums/showthread.php?t=47991&highlight=ffmpeg+slowdown

So no the slowdown from 333,340 to 4xx is not only amigaos, its
clearly visible booting the linux kernel too ... .
