I are looking at  Virtex-II Pro FG456 development board, which is very
similar to ML403 (Virtex-4 FPGA).  Virtex-4 have better DPS supports,
and slightly faster processor power, but it has no RocketI/Os support
yet, which is what we need.

We will be interested in collaborating and see how it's going.
