ok so here is a better guid on how to do it, note this is a guide and a rough one at that, i expect you can do it on your own or report back for slight modifcations also this is how i would do it, i am sure there are better ways and please tell me as i dont like the idea of having to set the CC varible everytime. it also looks long and hard but trust me its not, you may also want to read the thing throgh about 3 times and make sure you understand it all.
first we have to add to your $CC eviromental value, just append " -march=arm5", or " -march=iwmmxt" for the c*k series or " -mcpu=xscale" (recmomended)
next we edit the config.mk file and look for somthing that contains /lib/modules/`uname -r/build and replace it with <path to source>/build, or the better way is to
mkdir /lib/modules/2.4.20-zaurus
ln -s <path to src> /lib/modules/2.4.20-zaurus/build
you will also have to hardcode all values of `uname -r` and change it to 2.4.20-zaurus or else it will install the module for your computer and not put it where we want.
now we do a "make driver" and then "make install" which may or may not complain and cause wierd problems scince it does a depmod, you can get around this if you can work out the name of the file it creates and where it installs it to (might be in that config file but deffinatly ends in *.ko)
then its a simple matter of coping the file to your zaurus and placing it in the right subfolder of /lib/modules/<whatever directory is in here>/<wherever (mabey acx110)> and run a depmod. now all we have to do is figure how to make the pcamcia stuff load the driver on insertion which is not my area so you need to find someone who has had a wifi card that needed a bit of text editing to get working and adapt what they did to load your driver (make sure you keep note of the name)
