My original post doesn't seem to have worked on here, but I did get it working with 7.1, but it takes some hacking.
We have T440S, the only way I could get it to work was upgrading to WinPE 2.2, which 7.1 normally comes with 2.0 I believe. Also we are running 64bit WinPE using network driver: Intel Pro 1000
NDIS62 - e1c62x64.inf, e1d62x64.inf, and e1k62x64.inf
NDIS63 - e1c63x64.inf, e1d63x64.inf, and e1k63x64.inf
Second problem you will have will be Ghost will crash if you are using the SSD T440 Model. I had to upgrade Ghost to version: Ghost 12.0.0.4573
Both of these are probably not supported by Symantec and I believe would be resolved by updating to 7.5, which includes the newer WinPE and Ghost
