Just let me make sure I'm getting this right:

1). You don't have OOB available to you with your NAND part.
2). You want YAFFS changed to suit your special case.

It's all very well arguing that relying on OOB in all cases is a bad
idea - and indeed, it sounds like a good idea to support packing extra
data into pages on flash - but you seem very keen on pushing the idea
that it's always bad to use OOB. So long as logic is added such that
you can have different behaviour, I fail to see the problem here.
