Hello Pavel, here are the details about my setup.
 
In Openwrt, the madwifi package is built as kernel modules by selecting
kernel modules ----> wireless drives--->kmod-madwifi. On bootup, openwrt loads
the madwifi modules and /etc/config/wireless option is disabled by default.
 
As openwrt directly loads the kernel modules, I didn't use modprobe ath_pci and modprobe is
not built into the kernel.
 
After bootup, I did
root <at> OpenWrt:~# wlanconfig ath0 destroy
wlanconfig: ioctl: No such device
root <at> OpenWrt:~#
to make sure that any script might have created it.
 
and iwconfig shows
root <at> OpenWrt:~# iwconfig
lo        no wireless extensions.
eth0      no wireless extensions.
eth1      no wireless extensions.
wifi0     no wireless extensions.
root <at> OpenWrt:~#
 
followed by creation of wds link as
 
root <at> OpenWrt:~# wlanconfig ath create wlandev wifi0 wlanmode wds
wlanconfig: ioctl: Input/output error

root <at> OpenWrt:~# wlanconfig ath create wlandev wifi0 wlanmode ap
ath0
root <at> OpenWrt:~# wlanconfig ath create wlandev wifi0 wlanmode wds
wlanconfig: ioctl: Input/output error
root <at> OpenWrt:~#
 
Strange problem and I couldn't find the source of this issue.

Yes, I have used working version of madwifi in other distribution.
