It turns out that the bonding driver does indeed handle interface
redundancy to two separate switches. Martin was right and the kernel
documentation file (networking/bonding.txt) is packed full of useful
information. The specific section that deals with what I need is under
the heading "High Availability", option 2 "HA on two or more switches
(or a single switch without trunking support)". It uses link status to
determine that the interface is alive and uses one and only one at a
given time.
bonding.txt is well worth a good read.
