The config looks fine.

It's really not a happy bunny is it?  This looks to me like linux really isn't
happy with the NIC.  We should stop worrying about DHCP, this is one level
beneath that.

You bring the NIC into life, it says it's got a cable connected or not as it
sees fit, and I doubt it's ever successfully sent anything to the network.

I've seen suggestions that this is a sis900 driver bug and so could be fixed
by a newer kernel.  It could be worth downloading the latest fedora kernel RPM
and upgrading to that (although I can't see anything tempting in the
changelog).  Otherwise, could you try booting a knoppix CD?
