Jarod -

I managed to get the driver compiled using the current source (tar ball). i
had to fix the header change. but after loading the driver, i couldn't
associate my access point to the acx driver. also it seems to kernel panic
with this:

i didn't set WEP, i have a zero-security setup. also a process called
wpa_supplicant is running, and i can't seem to stop it. i have a hunch that
the driver would work if i can get wpa_supplicant to stop... any clues?

thanks,
thushara
