where do I find pcmcia Xircom IIps drivers?

["Mark Wright" <mwright@pro-ns.net>]

I've been using the stable Debian distribution with my Toshiba Satellite
CDT230, with no problems (well, with few problems) for a few months now.  To
enable sound and APM, though, I guess need to compile my own kernel.  But
when I compile the kernel, I don't see the xircom ii ps module that I need
for my pcmcia network card.  I don't see the code for it anywhere in the
/usr/src/linux (2.0.36) source code tree.  Can anyone tell me how to add
pcmcia networking support to my custom kernel?
