That's pasted straight in from the terminal window.  I wonder if
'omaininit' was originally 'domaininit' and something nibbled off the
leftmost character of each line?  The config file contains...

ex*     at pci? dev ? function ?        # 3Com 90x[B]

                             ...for the machine's 3c905 Ethernet card.
I'm having another go at building the kernel now.
