The ROM codes on Mac cards are really nasty. I would say that you hit
the memory somewhere which was not properly mapped for UNIX use (Of
course, Mac accesses all the memory directly).

I would say that the memory region 0xC4000000 has to be mapped in for
the code on your card to work. I do not remember all the details of
Nubus mappings, so I have little idea what is supposed to be there. If
you really want to understand what your card does, you have to
disassemble the code (for example, in MacsBug on MacOS side or ddb on
NetBSD side). You may also check what resources are defined in the
card's ROM. Slotman code has the routines and definitions to access
the data on the card, you can print the ROM data structures before
calling Init() from the card.
