I ran into a problem with the ISA Intel EtherExpress Pro/10+ in that
the ex driver used the hardware address to determine if the card is a
Pro/10 or a Pro/10+. If you have a Pro/10+ and the ethernet address
doesn't start with 00:A0:C9 then you need to patch if_ex.c to
recognize the new hardware address prefix as a Pro/10+.

Here is the diff I did to if_ex.c to get it to work for me:
