that's what Freescale is doing in its Linux BSP and it doesn't work 
without, at least on my board (8 bits width NAND):

	if (!this->badblock_pattern) {
		if (mtd->writesize == NAND_PAGESIZE_2KB)
			this->badblock_pattern = &smallpage_memorybased;
		else
			this->badblock_pattern = (mtd->writesize > 512) ?
			    &largepage_memorybased : &smallpage_memorybased;
	}
