Actually, this was incorrect: Moving to a freshly compiled 2.6.28.7 
resolved the issue *only when combined with the source routing 
configuration previously described*.

Without source routing used to shepherd demasqueraded packets to eth1 
(with a different, appropriate gateway), they still were leaving eth0 
and being discarded by the local router.
