MDT 2013 and Pentium 4 Systems

My firm is getting the first tablet machines in that will be Windows 8.1. This requires MDT 2013 and ADK 8.1. The problem is that we still have a few machines that are Pentium 4 systems, specifically Dell Precision Workstation 380s. The problem is that the Pentium 4 processor is not compatible with Windows 8.1 and ADK. The system will crash when the Windows 8.1 PE begins to load with the following message:

Your PC needs to restart.
Please hold down the power button.
Error Code:0x0000005D
Parameters:
0x030F0209
0x746E6547
0X49656E69
0X6C65746E

The resolution provided by Microsoft is to either upgrade the processor or downgrade to WAIK and MDT 2012.

There is a slight possibility of a resolution that I am going to work on when I get some time and that is to modify a WIM from MDT 2012 to point to the MDT 2013 server. I do not know if this will work or not. I did go in and replace the winpe.wim files MDT uses to build the boot wims with MDT 2012 winpe.wim files. MDT 2013 instantly failed. For now, the only two resolutions we have until we get the last of the older machines out of service is to have two different MDT servers, one for the old systems and one for the newer, or just create an image for the 380 and use the MDT 2013 for all of the rest.
