this is probably only half-way. well mlx driver loads but it complains again
on MMIO:
[    3.564844] mlx4_core: Mellanox ConnectX core driver v1.1 (Dec, 2011)
[    3.564845] mlx4_core: Initializing 0000:02:00.0
[    3.564967] mlx4_core 0000:02:00.0: Enabling sriov with:4 vfs
[    3.565087] mlx4_core 0000:02:00.0: not enough MMIO resources for SR-IOV
[    3.565402] mlx4_core 0000:02:00.0: Failed to enable sriov,continuing
without sriov enabled (err = -12).

so it seems, that pic=nocsr is a must now.
