i have a gericom webboy with a sis630 chipset for all stuff,grafics,sound and ethernet...there is a possibility to get eth0 running,just ignore yast2
that means just configure eth0 manually
i first typied
"modprobe DRIVER" to activate the driver
then i configured the basics of the network:
"ifconfig eth0 192.168.22.1 (or what ever) netmask 255.255.255.0 up"
then ifconfig shpuld tell you then eth0 is activated,if not start yast and do exactly the same stuff there (intergrate tnew hardware==> network card or something and then the basic network configuration with ip,device and all stuff ...)
after that linux should regard eth0 as running
i tried that and it works....
if you want to configure ADSL after that you should do it with yast2 in the TEXTMODE,than it works....
hope i could helf you a bit,even if i have no clue why that error occurs
