3.7 remaster with patched orinoco drivers

I have been working on a remaster of Knoppix 3.7 for about a year it boots to the default kernel 2.4.27. I want to patch the orinoco drivers so that I can run kismet. It seems that the PCMCIA drivers in Knoppix are built into the kernel. I can not find the pcmcia-cs. Can I download the source for pcmcia-cs-3.2.1 and compile it without having to recompile the linux kernel? Also the orinoco drivers seem to be in the /lib/modules/2.4.27/kernel/drivers/net/wireless/ directory. Is this where I would want to install and recompile pcmcia-cs? as opposed to /usr/src?
