In order to have a any pcmcia card seen by the system, you need the pcmcia diver loaded. To see if it is on your system, open a konsole, and navigate to a directory that will look something like this:
The exact path on your system will be a little different. The third dir in, '18.104.22.168-desktop-1mnb' is for my currently running kernel. Just go in one dir at a time, do an ls, you should be able to find your way. The pcmica modules are in the last 'pcmcia' dir.
The command 'modinfo modulename' will give you some idea of the module you need to load so you can 'see' any card. Once loaded, and a card plugged, then you can load the driver for the card.
Modules are loaded with 'modprobe nameofthemodule'. No news is good news. If you get no output, the module loaded. You can display loaded modules with 'lsmod'.
If you load up Knoppix, do a lsmod, you probably can figure out what the modules are you will need to load. Use lsmod, and with knowing what is in the pcmcia dir, you should be able to figure it out.
If you can not, post what you have in the pcmcia dir, the results of lsmod, and as much as you know about the card you are trying to get working.
Let us know, how you are doing...
