The above tests both work fine with the 2.6.20.1 sk98lin driver loaded as 
"modprobe sk98lin RlmtMode=DualNet".

I can change the MTU, add and remove eth2/eth3 from the bond, and up and 
down the interface.  It also works fine with different hardware (e100, 
e1000, tg3, bnx2).  Running both interfaces alone without the bonding 
driver also works (I can up and down the interfaces with no side-affects).
