FreeBSD has an iwarp driver for Chelsio's 10GigE cards and the kernel / iwarp side of OFA RDMA stack. To support IB you would need to implement the IB side of the OFA stack, finish user level RDMA support, and talk one of the users of IB on FreeBSD (NetApp & Isilon) in to opening up the Mellanox driver for a recent card. If you're open to the idea of iWARP it would "just" be a matter of finishing support for user-level RDMA. I'm sorry to disappoint.
