Enable multiple ISA ethernet probes at boot (old behaviour was to quit

once eth0 was found) - it is long since anyone shipped or built kernels
with all the ISA drivers compiled in.

This change will eliminate the need for adding "ether=...." at the boot 
prompt for a lot of users who build their own kernels and have multiple
ISA ethercards at standard (i.e. probed) I/O addresses.

Also got sick of counting zeros, so did a struct init cleanup,
i.e. {1,0,0,0,0,0,0,0,9}  -> {one:1, nine:9}
