It's supposed to but David wasn't sure whether this code worked properly.
Regardless of that, the blocks have their good/bad status marked in the
OOB area and nftl_format, while it doesn't necessarily handle it

certainly doesn't destroy that data.

If that area was bad, the chip would most likely be unusable- the IPL
code isn't smart enough to take notice of such things, so any chips that
had badness in the first 48k or so would have failed M-Systems factory
QC.
