i think this is ok, because only eth10 is receiving packets. traffic is 
flowing from eth10 to eth11

lsmod
Module                  Size  Used by
thermal                16780  0
fan                     6280  0

drivers are build directly in the kernel. i have attached the config file.

i can also give access to the test setup, if you want.

i have also tested kernel 2.6.18.3 and 2.6.19.2 on other hardware. same 
effect.
