Have a look at
this auction and then pick the right answer:
(1) The seller honestly does not know that this is a CyberstormPPC card.
(2) The seller has a CyberstormPPC card with a defective PPC cpu and is advertising the card as a MKIII, as in case the PPC cpu is damaged, the card would work the same as if it were a MKIII.
(3) The card doesn't work at all, hence sold as-is.
