I have tested two different kernels(2.6.32-34 and ) with two different
network adapters on the latest stable version of wpa_supplicant-0.7.3.
Attaching supplicant log output of this
Kernel: 2.6.32-34-generic Ubuntu 10.04
wpa_supplicant-0.7.3
Cisco Aironet PC-card adapter seems to be using ath5k driver
