Michael, I'm just throwing my two cents in here... in my experience header checksums that Wireshark picks up as being 000 instead of the correct value is usually because of TCP offload in the NIC... it's usually TOE doing its job, and you're not seeing the checksum being computed because the computation of the checksum is offloaded to the NIC hardware.
Crazy stuff I know... hopefully it helps you a little bit though.
