Thank you very much,

I had similar symptoms (dhcp failure on a P4 1.7G with a RTL-8139 nic) that was solved by booting with the noapic option. That is, at the boot prompt enter:knoppix noapic

In the startup logs (dmesg) there was a "NETDEV timeout message" that provided a clue to my problem.

Your mileage may vary...
