The BlizzardPPC is indeed the problem.
It's interface is undocumented and I recall that they found some weird behaviour.
They were able to completely cut out the 68K processor on the Cyberstorm but for some strange reason they weren't able to kill the 68K processor on the BlizzardPPC which would be a serious performance penallty because of the context switching.
I don't know if they allready solved that problem but they need to do some serious hacking and research to get the BlizzardPPC to work.
