I'd appreciate some advice on if I'm using OFED correctly.

I'm running OFED 1.4, however not the kernel modules, just userland.
Is this a bad idea?

Basically, I recompile the ofed src.rpms for:

dapl, libibcm, libibcommon, libibmad, libibumad, libibverbs, libmthca,
librdmacm, libsdp, mstflint

And install onto CentOS, upgrading the in-distro versions.
Should I also be compiling ofa_kernel ?
Could this be causing problems ?

As explained off-list, I'm running the most recent firmware for my
cards, although the release is quite old:

hca_id: mthca0
         fw_ver: 1.2.0
         node_guid: 0002:c902:0024:3c6c

         vendor_id: 0x02c9
         vendor_part_id: 25204
         hw_ver: 0xA0
         board_id: MT_03B0140001
         phys_port_cnt: 1
                 port: 1
                         state: PORT_ACTIVE (4)
                         max_mtu: 2048 (4)
                         active_mtu: 2048 (4)
                         sm_lid: 1
