Now that I have a C1K I'm also trying to do the same thing.
Did you have any luck ?
After some attempts I got the driver to cross compile but I only get the zd1211b.ko ...
I was expecting also zd1211.ko.
Anyway I copied the module over to my Z modules directory and did a depmod -a, but when I plug in the usb dongle nothing happens (even if I manually load module).
Doing an lsusb shows the wifi dongle (and led lights up) but ifconfig -a and iwconfig show no wifi device.
I assumed that it could be a power problem (USB OTG may not drive enough current) so I hooked up mu powered hub ... but no difference at all.
P.S. I got the driver from here.
