Sorry Ralf, I told you wrong on the FPU part. :(

<Sigh>  The Motorola roadmap I have been looking at makes
it clear that generation 1 PPC was 601 and 5xx but did not
make it clear they were different.

Ralf.. please put some of this CPU model data in the
PPC manual.

Thank you.  

Thomas have you made any progress on transitioning the
4xx to new exceptions so we can abandon the 4xx/old 
exceptions combination.
