openSuse 11.1 and ath5k

I've just upgraded to the latest openSuse 11.1. Everything went smooth except for some issues with wireless networking (Atheros wifi card with AR2413 chip) - not really problems of openSuse itself, but it turned out that:

• madwifi-0.9.4 doesn't compile with kernel-2.6.27 sources provided with openSuse (I haven't tried to google this problem or use madwifi from trunk)
• standard ath5k driver now works fine with my card (to my surprise) - no need to compile madwifi anymore; however
• ath5k doesn't seem to support WPA2; I had to switch to WEP for now :(
