My tests are not succesful wither. I tested on TQM8548; when booting Linux I see this:

The addresses where the read errors occur don't seem to be related to the bad blocks reported by Linux.
No. What does a "normal" "nand read" return when reading this complete partition into RAM? On PPC4xx it returned -117 here. I fixed it with the already posted patches for the 4xx NDFC ECC byte ordering. Perhaps the TQM8548 has similar incompatibility issues with the Linux kernel here too?
Best regards, Stefan
