Total frustration: Unable to start Cisco VPN on Mac OS X 10.4.10

I have had trouble using Cisco VPN for quite a while now. I have tried numerous uninstalls, reboots and log file scanning. Could not see anything. Had no clue. Discussed it with others, no solution in sight. Only getting the messages below. Very frustrating.

Could not attach to driver. Is kernel module loaded?
The application was unable to communicate with the VPN sub-system.

Until tonight, when I googled for a message from system.log. The first hit pointed to the Parallels forum, where someone suggested disabling the FireWire network interface, fw0. So I did as suggested:

# Shut down the FireWire network interface
sudo ifconfig fw0 down
# Restart the cisco vpn subsystem and verify that it works
sudo /System/Library/StartupItems/CiscoVPN/CiscoVPN restart &&  \\
sudo /usr/local/bin/vpnclient autoinit

And wow… it worked again.  It is so good to finally be able to log in to our work network again. Thank you, spud!
