-- same result with manual configuration.

I am making this "category kern", since the MD Nubus frontend is only a
shim that has not seen changes in a long time. The driver works just
fine on netbsd-4, so whatever rototilling the MI sys/dev/ic/smc91cxx.[ch] has
seen in the meantime is most likely responsible.

>How-To-Repeat:

Boot a 4.99.63 kernel on mac68k equipped with an Asante 10/100 MBit
Nubus card.

>Fix:
        None.
