I downloaded the prebuilt image from hardkernel, I did not build the
kernel myself. but hardkernel has an earlier release of the same kernel
version, which works fine too. I assume they would have committed the
change in the newer version..

that's what I don't understand as well...
the patched kernel shows the following:
$ uname -a

$ sudo ethtool eth0

1000baseT/Full
can it be that "EEE link modes" and the "normal" link modes are two
different things ?

I cannot check this easily at the moment..
