Hi Stijn,

You have, probably, copied RHEL 5.3 backports into ofa_kernel-1.4 
directory where the patches (RHEL5.0) already were applied.

In any case, it is better to take the latest ofa_kernel src rpm instead 
of updating source rpm coming from OFED-1.4.
The difference is RHEL5.3 support and some bug fixes (see git log).

Vladimir
