Cisco has released a new version (4.6.03) which runs on all single-CPU Tiger systems. There is still an issue with dual CPU systems, but this will allow Powerbook users to upgrade to Tiger if their only issue is the lack of Cisco VPN support.
Unlike previous Cisco VPN client installs, this no longer requires a system reboot after installation.

Note that you will need a Cisco login that has access to the VPN area. Guest access won’t get you to the VPN clients, but your IT staff should have a login with access if you use a Cisco VPN.
