PE 2950 III - SUU cannot update Broadcom NetXtreme firmware

We have a PowerEdge 2650 Gen III running Windows 2003 SP2 Standard Edition.  

We are using Dell SUU (SUU_740_Q42013_A00) to try to update the firmware of our Broadcom NetXtreme NICs.  The update fails very early on, throwing up a Windows error dialogue that says something is "not a valid 32bit application."  A peer suggested that he had had success in running the update directly from the Repository directory.  But the same thing happened when we tried that.  My guess would be that this is a known issue.  

The NICs in question are Broadcom BCM5708C NetXtreme II GigE

Here's the log:
