Imagine a couple of dead pixels on a chip. You can design software to continue whatever is on either side of the dead pixel, or remapping the information coming off the chip. One of the reasons that FF chips are so expensive is that you get far fewer viable chips off a 9" or 12" silicon wafer than from a smaller chip format. It is not just size, it is also geometry. There is more wasted space on the edges of the circular wafer. So, if Canon has found a way to reliably work around a certain number of bad pixels from their 1Ds MkII then they can indeed sell a FF camera at a much better price than before. A poor analogy would be the various clock speed chips from Intel. Not all the chips will clock at their rated speed, so you sell the slower chips for less. If you don't, then you have lost a fairly large percentage of your production turned into scrap.
