OK. I thought I could only use the FW version on the IBM table (I
mentioned before) and not the one from the link you provide.

Yes, it was in fact an endianess issue. I had some "wrong" pointers
and then was being mislead by the printed values.
Took a while but I learned something in between :)
I will install ofed 1.3.1 to be on the stable side of the force.
Many thanks, in particular to Dotan for his review and will to help me.
