Sure, you can change stuff *within* a module, you just can't create or 
delete new modules.

It depends.  If the processor can transparently switch between two modes 
(e.g. arm and thumb) then you probably want some sort of attribute that 
you add to each function that specifies which target to compile for.

I don't think that the cell supports this, so it probably wants two 
modules, one with SPU code one with PPC code in it.
