Well Folks - I have Ethernet and the Atheros Wireless working on Leopard on my T60!!!
mfbernstrein is exactly right in how to do this.
adding a line for your device ID under IONameMatch (the line is "<string>pci168c,1014</string>").
I then followed the guide that is here on how to load a kext.http://forum.osx86scene.com/viewtopic.php?f=16&t=229
It DID NOT work until I rebotted with a -f.
Thanks again mfbernstein!
I will post a review of this here as I test.
I just wanted to say this was exactly what I needed. I have been working on my Vanilla Retail install for Snow Leopart 10.6.4 on my T60p. It had the Intel wireless adapter so I purchased an IBM "Whitelisted" Atheros Wi-Fi adapter off of ebay. After the install I couldn't figure out why my wireless wasn't showing up, even though everything I've read said it should work Out of the Box.
So all I ended up needing was:
1) Found my Device ID (168e 1014) from linux with lspci -nn
2) Added "<string>pci168c,1014</string>" to /System/Library/Extensions/IO80211Family.kext/Contents/PlugIns/AirPortAtheros21.kext/Contents/Info.plist
3) ran sudo touch /System/Library/Extensions
and let the kext cache rebuild
After a reboot, it was good to go!
