There were some changes on net-next-2.6 for tg3, you could try to revert them...
(They are working just fine on my machine, but I suspect you have a different chip)

tg3: Add MDIO bus address assignments
The 5717 is a dual port chip that has a shared MDIO bus design. While
it is impossible for one function to interface with the wrong phy, that
function still needs to know which MDIO bus address to use when
interfacing with its own phy. This patch adds code to determine which
MDIO bus address to use.

tg3: Assign rx ret producer indexes by vector
When RSS is enabled, the status block format changes slightly. The
"rx_jumbo_consumer", "reserved", and "rx_mini_consumer" members get
mapped to the other three rx return ring producer indexes. This patch
introduces a new per-interrupt member which identifies which location
in the status block a particular vector should look for return ring
updates.
