2.6.5 panic while unloading cisco_ipsec

Please let me know if I'm posting this in the wrong place. I get a
kernel panic with kernel 2.6.5 (compiled with gcc 2.95.3) when I try to
unload the Cisco VPN client's (4.0.3b) cisco_ipsec module. I know it's
a binary-only module, so I'm not sure how much help this will be, but
here's the text I managed to pull off the screen when I tried rmmod'ing

(Not sure if there is anything above this, this is all that fit on the
screen, and I didn't find anything in the logs)
