It looks like skge driver enables different device than probbed.
Maybe you've something old/wrong about eth0/eth1 in /etc configs?
You can also try with netdev= or pci= kernel parameters.
If no result - resend it, please - maybe with some debugging on
(modinfo skge). BTW - netdev seems to be preferred for this.
