Yep. That is the conclusion that we came to also. 
A work around for now, one can just remove the arping check 
in ifup if the device is an ib device. Not perfect, but
allows it to work for ib devices and the normal ifcfg-xxxx scripts. 

Something like,

    if [ "x`echo ${REALDEVICE} | sed -e "s/^ib.//"`" != "x" ]; then
        if ! arping -q -c 2 -w 3 -D -I ${REALDEVICE} ${IPADDR} ; then
            echo $"Error, some other host already uses address ${IPADDR}."
            exit 1
        fi
    fi
