That wasn't really the issue: the problem was that a lot of the important
libraries were in ROM (that is, the code was in ROM; the library struct &
jump table were copied to RAM IIRC, otherwise SetFunction() wouldn't've
worked). Certainly exec.library, intuition.library, dos.library were all in
ROM.
