In most cases both the patches and the backport headers are used

Right, since OFED 1.4.1 and SLES11 are both based on kernel 2.6.27. Note
however, that sometimes the includes are patched by the backport patch.
This is typically done in cases where the include file is actually
checked out by the ofed_checkout.sh script - see
ofed_scripts/checkout_files for a list of these.
