Pull following change from marc-pcmcia branch: 

> revision 1.1.2.4
> date: 1997/10/15 01:01:57;  author: enami;  state: Exp;  lines: +10 -8
> Use bus_space_write_1() directly instead of NIC_PUT(), since
> - same io port is accessed by bus_space_read_1() in the same function, and
> - can bypass sc_reg_map[].
