The problem is a combination of
  Kernels after about 2.2.14 call the probe routine once for each of
     the 8 drivers/net/Space.c entries, instead of just once.
  There is no way to register exclusive use of a memory region, such as
    check_region() / register_region() in I/O space 

The work-around is to compile eepro100.c with -DUSE_IO_OPS when compiled
into the kernel.
Using I/O operations also avoids the timing bug in the i82559 when doing a
RxAddrLoad command.
