I have two wireless router:
1.Buffalo wzr-g300n, bcm4704+bcm5325F+bcm4306,4M flash/16M RAM, I change the bcm4306 mini-pci wifi card with bcm4318, no problem.
2.Buffalo WZR-g54, bcm4704+bcm5325+bcm4306, 4M flash/64M RAM

I want to change the wifi card with atheros cards. I  tried 3 mini-PCI cards:  atheros ar2413 / ar5212a( HP w500) /ar9160 (MB82 ) on  both router, but these 3 cards can't work, NO wifi function!  I have tried the newest version openwrt and dd-wrt, all failed.

under the new version openwrt, there is no lspci command, Under dd-wrt , no lspci command too, but under dd-wrt, I use "cat /proc/pci" command , I can see the atheros card is in  PCI devices list.
I look at the "ath_hal-20090508.tgz ",  in file  ah_devid.h, I can see the right DeviceID of my 3 atheros cards.

so, who knows why?

Did you install kmod-madwifi after changing the cards? You also need to regenerate the wireless configuration

rm /etc/config/wireless; wifi detect > /etc/config/wireless

After I changed atheros wife , I  flash the openwrt BCM47XX version. Is this version official  support atheros?  Does openwrt bcm47xx version need install kmod-madwifi ? and need regenerate the wireless configuration ?

Yes, you need to do install kmod-madwifi, yes you need to regenerate the configuration.

My mini-PCI cards is AR9160 (MB82).
I installed kmod-madwifi , No use. and I also tried another driver kmod-ath9k, faile too.

this is the dmesg
