* i386/i386at/i386at_ds_routines.c (emulation_list)
	[LINUX_DEV && CONFIG_INET && CONFIG_PCMCIA]: Add the Linux pcmcia
	emulation structure.
	* linux/dev/glue/net.c: Include <linux/wireless.h>.
	(device_get_status): Rewrite function.
	(device_set_status): New function.
	(linux_net_emulation_ops): Add `device_set_status' at the appropriate
	position.
	* linux/dev/init/main.c (linux_init) [CONFIG_PCMCIA]: Call pcmcia_init.
