Ok, this is supported by the sm(4) driver. The NuBus attachment stub
for it is in sys/arch/mac68k/nubus/if_sm_nubus.c.

You only need to follow the "Identifying your card" section on that page.

The difference between the two cards already supported by the NuBus sm(4)
driver is the offset of the EEPROM containing the Ethernet MAC address.

You could have a look for it using MacsBug.
