You cleared that up for me. The driver I'm trying to install is for a "Broadcom Corporation BCM4313 802.11b/g/n Wireless LAN Controller" which is not part of the kernel at all. The readme for the driver is at [1] and I basically compile that driver against the kernel headers which I've built. That driver expects CONFIG_WIRELESS_EXT to have been on when the kernel was built so all is good, after your explanation. Thanks as well for including pointer to PCMCIA_RAYCS I got that enabled which as you said enabled the switch I needed. It's just as well because even thought the help info mentions "Toshiba" vendor I couldn't find that where I thought it was meant to be in make menuconfig. No matter PCMCIA_RAYCS did the job.
