so I get a very similar bug on edgy with madwifi-ng (but i've always been a madwifi-ng user because even in dapper my card wasn't supported by the old driver).
for me the lockup happens when joining or leaving networks. the keyboard is pwned. the mouse still works (moves around) but i can't get too far with that. clicking on stuff generally doesn't work.

i know no way to get a dmesg of the problem.
