While putting together a Vista image using MDT (RTM), I assembled a group of drivers to support a number of HP machine models.  After assembling a list of machines I downloaded a number of drivers directly from HP's website, and added them into the out-of-box drivers in MDT. 

I had several machine models which were blue screening after the first reboot, and finally determined that  the Blue Screen was the result of a driver I had included to support ATI graphics for a nc6400 laptop.  The HP file was SP36487 and included the ATI video driver to support the laptop, and also a small driver identified as a ATI PCI Express (3GIO) Filter Driver, and was accompanied by MSI which when run was identified as a North Bridge Filter Driver.  

When I disabled this driver in MDT identified as ATiPCIE.inf with a file version 1.00.0000.1 - the blue screens stopped.  What made this really hard to resolve was that fact that the blue screens occurred too quickly followed by a reboot to allow me to see any stop messages.

Hopefully this experience will prevent others from spending significant time trying to resolve the same or similar issues.
