//it's gross for this not to be the full 32bits.
//Uhh I mean, I guess the bus is physically smaller.. but the cpu's view of it is larger...
//So... I guess no matter what we do, some badness will propagate. This is probably least bad.
//Anyway, the disassembler, for instance, must have been masked down to size, since code can run from FFxxxxxxxx...
