I have a top 20 list as at 27-Sept-2007, but I do not think it will help any:
I'm assuming one or more top 20 holder(s) or other large holder(s) are caught up with Primebroker, but we will not know who until they or UXC make an announcement.
I'm guessing it must be someone close to UXC, or at the very least someone who has informed UXC of their Primebroker exposure. Or maybe ANZ told UXC.
