That's what I understood from the developers notes. But I'm a bit puzzled
on the interrupt side. Nubus devices interrupt by sharing one VIA2 interrupt
and raising a bit in one of the VIA bidirectional ports. PDS devices see the 
main bus directly and can use any interrupt level.

Ok, let's try that. From what I read in the source code, the Nubus code 
should probe for Nubus devices on all Macs, so that step seems to be done.
The kernel should print a line 'Probing for Nubus devices ...', are there
any Nubus devices reported following that line? That should sort out
question #1. Did you already look at the BSD source on that issue?

CC: to linux-mac68k ... that list is more appropriate than debian-68k.
