   The values used in LANCE_OBIO and LANCE_IRQ seem to be empirically
   true for the correct IRQ and address of the lance registers.  They
   have not been widely tested, however.  What we probably need is a
   "proper" way to search for a device in the sun3's prom, but, alas,

   There are more assumptions made throughout this driver, it almost
   certainly still needs work, but it does work at least for RARP/BOOTP and
