Here is the capture from the uClinux boot. What do you make of it?

The fact that you are getting a different bad reloc reported each time still suggests to me a memory corruption error. Or at least, that these bad relocs are a symptom, not a cause, of the real problem.
Given that you have a highly non-standard system setup (dual CPU, multiple memory controllers etc), there are just so many places you could have done something slightly wrong, it's really not possible to debug this via email.
You'll probably have to solve this one the hard way - start peppering fs/binfmt_flt.c with printk statements, and prepare to learn a bit about how the flat loader works. XMD / MDM and mb-gdb debugging the kernel will also be helpful.
grep through binfmt_flat.c to find the error text, see what conditions cause it to be triggered - put printks in the code leading up to that, all that business.
Add "FLTFLAGS+=-v" to the app makefile (user/simpleinit/Makefile in this case), try to correlate the verbose elf2flt output with the bad reloc errors you get when you load the app.
