Driver for RTL818x based WLAN adapters

I'm using fedora core 5 (kernel 2.6.15). My wireless
card is ZyXEL PCI (Realtek 8185 rev 20). I don't have
problem compiling the drivers and the ieee800211 drivers.
When I try to load the drivers using insmod there are
problems with ieee80211_crypt_tkip-rtl.ko (unknown
symbol "wireless_send_event" and a lot of unknown
symbols when I install the driver rtl818x (ieee80211_wx_get_name,
ieee80211_reset_queue,
ieee80211_wx_set_encode, etc, etc)

Can you help me to fix these problems?
