Ok Fabio, nevermind.. I trust the pure intentions of the kernel community
and yours. For one moment I've lost the compass (we say this in Italy, I don't
know if it is valid too here) and I apologize for unfairness (I've spent months
on this board! urk!)

Returning on the subject, I was not the first owner of the i.MX pdk board in my
possess, and since the freescale NAND driver uses a private OOB schema, others
could have soiled my nand chip overwriting the Bad block bits in the OOB.

The things are two: 
1- I have to clean my NAND chip. -> the bad block scanning could 
   get rid of true Bad blocks.
2- Why the mxc_nand driver do not read your bbt as the 
   bootloader do?
   What version of redboot are you using?
   I am Very curious on this disagreement..!
