Hey guys,
This is definitely fixed for SP1.
Just wanted to make everyone aware of that. As ZMan pointed out this seems to be affecting a very small number of hardware platforms at this time. In fact, when we shipped we hadn't found any hardware that didn't work. VMware had some problems, but we chalked that up to a VMware thing (because "real" hardware didn't fail) and opened a ticket with them with inquiries.
At any rate, we've got a solution in place that will ship with SP1 and fix this issue. I'm sorry for any difficulties in the meantime!
Thanks!
