Stupid question but the MAC addresses on the cards are different aren't they? Could you also double check that the xid values differ on both machines, this is shown on the line:
IP-Config: eth0 UP (able=1, xid=07196018) ^^^^^^^^
Both MAC and xid should be different.

The MAC address is embedded in the chaddr field of the request packets.
This trace does not contain any DHCP NACK responses that were shown in the DHCP server log (annotated in the log below). Are you sure it is behaving exactly as before (i.e. is the DHCP server showing the same messages being transmitted, including the NACKs)?
The kernel appears to be working correctly in this case.
Thanks Mark
