* network/Makefile.am, network/README.cs8900, network/cs8900.c,
	network/cs8900.h: Significant update which corrects the problem
	where the cs8900.c file was actually the BSP glue.  Joel did
	some hacking so this file will compile.  Previously it required
	providing a target.h file to compile.
	* network/cs8900.c.bsp: New file.
