Another thought about this: surely the act of invoking normal functions 
within OpenBIOS is enough to cause the register window to shift. Does 
that mean that the CIF needs to take a snapshot of the registers upon 
entry and then map this snapshot to forth words such as %g0, %g1 etc.? 
Otherwise it all seems a bit useless.
