I have a very similar problem.
I get the eth0 not present also; however, I am using Whitebox Linux, which is Red Hat Enterprise Linux compiled by whitebox.
Only thing, I've never had my card detected by linux.
when I do the lspci, I get:
02:01.0 Ethernet Controller: Linksys Gigabit Network Adapter (rev 12)
I tried homey's suggestion, and still get the same thing.
the sk98lin has been compiled per the linksys directions.
please help this
I am at a lost for what to do next
