Based on that thread I would suggest using ethtool to mess around with the various offload setting on the physical interface and/or the bridge, could you have a play and see what happens? The git log of net/dev/core.c since 2.6.26 shows a bunch of work in this area but no one changeset leaps out as being an explicit fix. There's a changeset against drivers/net/tg3.c which clarifies the use of checksum vs GSO offload but I'm not sure it actually changes anything.
