Here is an email I sent out last week.....it may apply to your problem... snip... After I got the "instoco dasda1" to run ok... I did not have an "eth0" device activated when I booted the new system.
I did an lsmod command and saw that the lcs.o mod was not loaded. So..I did an "insmod /lib/modules/2.4.9-17tape/kernel/drivers/s390/net/lcs.o" and it loaded the driver, but it gave me a msg saying that I was "tainting" the kernel?? Then I issued an "ifup eth0" and I had my eth0 device!! After next boot, I was back to no eth0 device, so I added the lcs.o mod to /lib/modules/2.4.9-17tape/kernel/net/ directory Rebooted and ....I had my eth0 device!!
