I should probably elaborate a bit more. I myself have the same card:
ogasawara@emiko:~$ sudo lspci -vnvn | grep "Wireless" 0c:00.0 Network controller [0280]: Intel Corporation PRO/Wireless 3945ABG [Golan] Network Connection [8086:4222] (rev 02)
I was able to reproduce the lock-up without linux-backports-modules-jaunty installed. After installing linux-backports-modules-jaunty I no longer can trigger the lock-up. Would be good if you could confirm as well. Thanks.
