Did you ask at Fedora too? Because I don't remember any discussion between the developers and PPC is one of our supported architectures.
I'm not sure Fedora as a community-based distribution is going to stump up the quarter of a million dollars to produce the number of boards we want to produce at the price we want to sell them to everyone ($2500 is a lot of money for such a board, but 100 units is very very low compared to how many IBM JSxx blades are sold every month.. which Fedora probably has an easier time justifying developer support for)
I have thought you were looking for orders also from individuals, not only organizations. And some developers could be interested. Redhat employees have surely access to IBM hardware but the community members are using PowerMacs, I would tell.
I know that doing a bussiness is hard, so thank you for your effort to create a real PowerMac alternative. I was decided to buy one for the first annouced price $1500.
