You forgot to mention the PCI-e slot with only 4 lanes and a processor without AltiVec instructions. Oh and the memory benchmarks I've seen are no faster than my PC133 equipped Quicksilver.
Overall, there's not much difference between this board and the P2020 Freescale board Andreas and I discussed (except the Freescale board is only $595 with a hard drive pre-loaded with Linux). And we dismissed the Freescale offering because it had many of the faults present in the SAM460EX.

I'd love to see some new MorphOS hardware, but Andreas' posts have convinced me that we need to consider the P5010, P5020, and T5020.
If we could base something on one of those and charge SAM level prices for a board competitive with the X1000 I think we'd have a winner.
