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
