I have a feeling there is a bug in the ROM code for certain machines 
which is patched by the MacOS via an INIT.  Since we don't load these 
INITs in NetBSD we run into the bug when using the ROM code.  The table 
size isn't really the problem.  We're tried making the table larger than 
the total number of resources in the ROM itself and we still see the 
error on certain machines with certain ADB devices connected.  This makes 
me think the ROM code gets hung in a loop loading resources that it can't 
break out of without the special MacOS patches.  This all goes away with 
John's HWDIRECT code though and is one more good reason we need to move 
in that direction.
