This looks like a pathing problem. It has to get initrd.img and pull it into 
the ramdisk. initrd probably needs an absolute path, as in initrd=/initrd.img
I'm not familiar with NFSROOT, but should that not include a mountpoint?
Also there are two different spellings of Fedora_Core_2
hope this helps...

I don't think it got that far...
