Well, some of this is in fact handled by my SLOTMAN code, which
implements a complete version of the Mac's slot manager (and enough of
the device manager as required). NuBus probing actually goes out to
each card and executes the cards' PrimaryInit and SecondaryInit routines
if they're present.
However, there are some bugs dealing with the "simulated" slot devices
that several of the newer M68K Macs use.
