Thanks again, but actually I was able to make that thing work. It seems that this card is working with Cacko ROM – I'm just added it's entry to file hostap_fw.conf in /etc/pcmcia. Entry is gotten by console command cardctl ident
IDK if it matters, but I named my card as "Gemtek WL-672". Also I'm added a SanDisk Connect+ firmware to etc/firmware directory, file sf010704.hex, and installed sandisk-plus_arm.ipk. After this and a couple of reboots Zaurus recognized card fully and is able to made a connection. Unfortunately, Cacko ROM kernel not supporting WPA, so only the unsecured connections are recognized (made a access point from my Android phone).
