Some ISA v2.03 Vector Multiply instructions marked to be ISA v2.07 only.
This patch fixes it.
and MacOSX 10 is also fixed.
There are of lot invalid writes when openbios is loaded :

Mark,
shouldn't we model the FW region with RAM instead ?

I don't believe so. The original aim of OpenBIOS was to run as a free replacement
firmware on real hardware, so what should happen is that OpenBIOS should copy at
least the bss section into RAM early in the startup process. There could well be
errors in those calculations as I have tried to adjust them over time though.
ATB,
Mark.
