When configuring the tunnel interface on Sup720 it tells you if it 
will be hardware or software switched.

7609-1(config)#int tunnel 1
7609-1(config-if)#tunnel key 0
%Warning: Feature not supported in hardware. Tunnel1 packets will be
software switched
7609-1(config-if)#no tunnel key 0
Tunnel1 packets will now be hardware switched.
