[opensuse] network unavailable (lenovo z570)

My opensuse 12.1 on lenovo z570 cannot find any network interface.
There are indications that the issue could be related to some kernel
module not being loaded or to conflicting modules, possibly connected
kernel 3.1

Here you can find my relevant log files

Any hints?
About 'lsmod' command:
Are kernel modules to manage cable (eth0) and radio wave (wlan0)
interfaces diplayed by my 'lsmod' output?
Can one conjecture of any couple of modules clashing?

Thank you
