But using this port is pointless, because it'll slow the connection
down.  What's the actual problem with using the netdevice?  Did I miss
something in the archives?

vpnc seems to work just fine in the normal 'hso' configuration with the
tty being the control port and the netdevice being the data port.

What encapsulation or NAT traversal method are you using?  Does 'vpnc'
work for you?  Are you using the cisco binary kernel module?
