thank's for the hint. I could now fix unit cpu.pp
The problem was the calling convention
(all assambly routines assumed parameters on the stack - but now they 
are in registers in fact)

But {$calling oldfpccall} didn't work (neither on top of the unit nor in 
interface or implementation)

I had to define the calling convention behind every assembly routine
(eg: function getPITValue( var val: int64): bool32; assembler; oldfpccall;)

Now I hope this will help with graphix too.

regards Peter
