Wireless problems

I've just read about wireless (post by Terry) and thought that I might
set up WiFi on my ThinkPad T40p running Fedora Core 3.

I checked (using lspci) that I have a Atheros chip and downloaded
madwifi from CVS.

Running make worked (although with lots of "undefined" warnings).

But when I used insmod to load the modules I could only load wlan and
ath_hal, but not ath_pci:

[root at localhost madwifi]# insmod ./ath/ath_pci.ko
insmod: error inserting './ath/ath_pci.ko': -1 Unknown symbol in module

The 'Hardware Browser' tool still does not see my wireless PCI card
after running insmod. And iwconfig doesn't seem to find any wireless
extensions.

Thanks in advance for any help on that.

Christian



Here's the output of lspci, make, insmod, lsmod, iwconfig:
