Well, I tried it myself without succes.
I got myself Snow Leopard 10A380 and extracted the IO80211Family.kext, from this kext I took the AirPortAtheros.kext.
Then I got AirPortAtheros.kext and put into the IO80211Family.kext on my 1000HE, repaired permissions and rebooted. No wireless.
Then I decided to replace to whole IO80211Family.kext, repaired permissions and rebooted. No wireless.
Also checked the Info.plist inside the AirPortAtheros.kext:

I believe pci168c,2a belongs to the AR9280, so it should be supported?
If anyone is interested in the IO80211Family.kext, I could upload it somewhere.
Has anyone got any idea what I could still try?
