I had a similar problem with the dell sata ahci drivers, here was the solution that worked from me.

"Go to c:\doc&sett\all users\application data\symantec\ghost\template\common\windrivers folder and search for the string "2922". If you open one of these INF files you'll see that Class=hdc instead of usual Class=SCSiAdapter. Change that line ro read Class=SCSIAdapter then go to the root folder of this driver and delete file called drivers.manifest.txt. Restart GBW, go to Winpe editor and select any Winpe config. When you go Storage drivers tab you should see this driver appearing on the list. Select it and go OK. Once finished your Winpe preos is ready to be used from the Console."

I have edited the string to represent your problem.  This was sent to my by the very helpful Eugene.

Hi Mikster,

AHCI controller drivers are generally not a problem and can be ignored but because our VP building code tries to help you by not going into Preos that will potentially not even boot or not connect (ie. no network or mass-storage drivers) hence why you get this error.
Fix is simple enough: a) either update a driver and auto-rebuild pci.manifest.txt from GBW or b) ignore particular device ID as described here.

Unfortunately a) will not work for you. I have posted updated Intel.82801 driver to a few people but ID 0x2922 is still not included in it so you only option is b).

We will be smoothing the process of adding extra "to skip or to ignore drivers" to GBW in the next LiveUpdate.

Cheers.
