I don't use wpa as my other interface at home doesn't support it
(stupid windows only crap) and otherwise I am on public networks. But
I've seen ilw3945 go terribly wrong. once in my testing modprobe -r
iwl3945 brought on a kernel panic and locked the laptop up hard (truly
locked). ouch. 

IOW, welcome to sid... ;)
